Top 2 Profitable Purchases of 2017

2017 isn’t over yet but I guarantee that nothing else I buy in the next 3 months could surpass these 2 products. Read on if you want to:

  1. save time for what’s REALLY important
  2. save energy
  3. maximize your productivity and efficiency


I have two kids, a 3 year old and 5 year old, which I home-school and I also do some work from home. So with the 2 kids, you can imagine what kind of mess I have to deal with daily on top of my regular chores. I used to use a cordless stick Dyson vacuum for all of the little messes on our hardwood and spent about 15 minutes per day sweeping/vacuuming only in the kitchen/living room area. On the weekends I would spend an additional 45 minutes vacuuming the carpeted areas in the house and the bedrooms.

15min x 7 days = 105min + 45min = 150min/week x 52 weeks in a year = 7,800min /60min = 130 hours per year /24 hrs = 5.42 days a year


That means I spend almost FIVE AND A HALF DAYS in a year vacuuming or sweeping. OK fine, some days I’m too tired or lazy and don’t vacuum / sweep at all so lets round it down to five days a year (reduced by 10 hours). That is STILL FIVE DAYS OF MY LIFE of which I can think of much better ways to spend my time!


So lets say you would rather have someone come into your home and vacuum for you. The average hourly rate for housekeeping in Edmonton according to is $16.44 x 130 hours per year is $2,137.20 (or rounded down again to 5 days = $1,972.80/year).


PURCHASE # 1 – iRobot Roomba 860 or iRobot Roomba 890 <— we have the 860, not the 890 so I can’t comment on how well the 890 works, I just wanted to point out that 890 was wi-fi capabilities and you can control it with iRobot’s HOME App.

This is a vacuuming robot (there are higher end versions which maps out the layout of your home but we purposely chose 860 as it doesn’t have Wi-Fi)  You can schedule the Roomba to vacuum every day of the week at a certain time or just press CLEAN when required. These 2 also have the tangle-free rollers/brushes which the older versions DO NOT, so they are much easier to clean than the older versions. We had an older version with the brushes that have bristles so I had to cut the hair out of the bristles each time I cleaned Roomba and eventually I got tired of cleaning the bristles and decided sweeping is faster.

  • The extractors are tangle free now – no more bristles, the hair just accumulates in rolls at the end which just fall off when I clean the extractors
  • There is a little Virtual Wall Barrier that you can turn on to stop Roomba from going past certain points or around a certain area
  • If it detects dirt in an area Roomba concentrates in that area. Cleans under beds, furniture and along walls
  • Does not fall off of the stairs (cliff detector)
  • Lets me know when the debris bin is full
  • Comes with High Efficiency Filters captures 99% of dust, mites and allergens as small as 10 microns
  • Once it’s done it goes back to it’s charging station to charge up for the next cleaning session


PURCHASE # 2 – iRobot Braava jet 240   This is a mopping robot. You just attach a a cleaning pad (I bought reusable ones here), put WATER in and press clean. Once it’s done you press the button to eject the cleaning pad.


  • 3 cleaning options: Wet mop, damp sweep, and dry sweep
  • Great for cleaning “small spaces” like kitchens and bathrooms (I clean 1 area at a time, charge up/refill the water and continue cleaning the next room)
  • Systematic pattern cleaning
  • Small and compact to clean around toilets, under beds and cabinetry
  • Does not fall off of the stairs (cliff detector) and doesn’t go up rugs
  • Super quiet


The cost of hiring help for 5 days a year just to vacuum (and not mop) is almost $2,000/year. This alone almost covers the cost of purchasing TWO Roombas and TWO Braava jets! My previous Roomba is still working and is now 8 years old so these purchases are definitely worth it (plus the amount of time it saves me each year is worth much more to me than the $2,000 each year).

We would love to head from you about what your profitable purchases are.



The Best Low-Cost Canadian Index Fund



  1. 8.2% return in the past 5 years
  2. Lowest MER fee for good return at 0.39%

The Catch?

  1.  Requires a minimum of $50,000. This is how they keep their fees low! If an investor comes in with $100 they take up the same amount of time and resources as the investor who comes with $50,000 so that’s why funds at all other banks and firms that cater to the masses have much higher MERs.  This higher entrance fee keeps too many people from having it. Too many people indexing causes mispricing in the efficient market theory.

How much difference can half a percent in additional MER fees make?

If you are paying half a percent in extra MER fees, this could lead to nearly as much money paid in fees as your total contributions over your working life.  $1 million lost in fees over 40 years on a $1 million of contributions.  If the fund is giving returns that are less than or only meet CIBC’s premium index fund, there is no reason to pay the extra fees.

If you already maxed out your investment in your own business and have $50K liquid cash then call your nearest CIBC branch to set it up:

The Most Efficient Way to Run a Business


Our new office hours are Monday to Friday 8am to 1pm. If it is inconvenient for you to drop by during our office hours you can also arrange a time for someone to pick-up your documents after 1pm. (Edmonton area only)

Background and Framework for Efficiency

  1. Focused 5 hour work day: We had the focused 5 hour work day from 2010-2013 and started it again with one employee in March 2017. We have seen first hand that our focused 5 hour work day reduces absences, stress and increases efficiency. Shifts under 5 hours, employees are not entitled to any breaks.  Lunch and breaks during the typical workday are not used to re-energize or restore attention.  In our office’s case, they are spent eating lunch late at our desks in front of the computer, while other workplaces time is lost strolling in late after getting caught in line at Tim Hortons. Back in 2010-2013, as owners, we worked 10+ hour days and we were much more efficient running two employees on separate 5-hour shifts (8am-1pm and the second person from 1pm-5pm).
  2. Unless you are financially independent, you should be working rather than hiring out the work. No one will ever do a better job than you, and no one will ever care about your big picture as well as you. Only farm out things that can be completed more efficiently through unique skills and economies of scale (Accounting, bookkeeping vs. doing it yourself). Due to minimum efficient scale, the cost/technology would not make sense for an individual to specialize in something that is not directly related to their ability to generate revenue.
  3. The most sustainable payroll solution is that if you pay someone $20 per hour, the employee should also “pay you” at least $40 per hour (giving you $20/hour as their contribution to overhead). You have to account for the payouts you are responsible when you have staff: statutory holidays, 4% vacation and eventually termination pay.  Profit per employee is an important metric that our 3rd iteration of SwissBooks will measure and report to you.
  4. Consider converting any full-time staff you have to focused 5-hour shifts. If you are open longer you could consider running back-to-back 5-hour shifts as we did 2010-2013.
  5. Bring efficiency and focus into your life is efficiently articulated in this appropriately titled book: Efficiency: Get Rich Without Giving Up Your Life.  It will also tell you how to start an online business or make money with affiliate marketing.
5 hour Office Monthly Income Update
  1. $10k+ after-tax per month of passive income from a 5% net return on $2.5 million.
  2. $14k+ average after-tax income from hours worked. (Total average after-tax net income $24k+/month+).
Asset Class Update 2017
  1. 20% insured real estate (max 30%).
  2. 10%  stock (max 20%) maximum 3% of this initially invested in any one company.   Be prepared to hold on to stocks indefinitely: choose strong brands that will be around in 20 years.
  3. 15% CDIC protected cash (minimum $50,000)
  4. 15% CDIC protected guaranteed term deposits
  5. 35% scalable assets

Dear valued SwissBooks clients,

We would like to inform you of a billing change effective September 1st, 2017.

Since launching THUT Accounting in 2006, our constant improvements equip you with the most innovative accounting solution, which is why this billing change will also support the ongoing development of new value for your business.

The all-inclusive flat fees including GST are as follows:

$8,800    Industry: Annual expenses over $1 million
$7,100    Enterprise: Annual expenses between $450k and $1m
$5,600    Venture: Annual expenses between $200k and $450k
$4,700    Boutique: Annual expenses between $100k and $200k
$3,900    Micro: Annual expenses less than $100k
$3,200    Startup: No payroll & revenue below $380k

Save 1 free month of bookkeeping for every new client you refer to us.  Your referral will also get 1 free month of bookkeeping and you’ll receive a thank-you for introducing them to a service that at a cost of 1% or less, legitimately reduces costs by 3-30%. 

If you do not report at least $90,000 of annual net income and have at least 20% pre-tax margins, then SwissBooks is not helpful and it is not fair to recommend a product that is not going to be tailored to your needs. It may be in your best interests to dissolve your corporation and save yourself unnecessary accounting fees by filing as a proprietor.  Alternatively, the easiest ways to turn it around are either through focusing on either recurring revenue or big ticket item sales. 

We want to thank you for your continued business and we are committed to working with you to help save you money, and help you net $20,000+ a month after-tax in your business.

Best Ways of Thinking Differently

There was an excellent comment in our highly popular post on Choosing Your Market & Pricing. Thank-you “dicky dee” for creating this idea and everything in quotes are his words.

  1. Most people think “follow your passion” is sound advice. Successful people often attribute their success to doing what they are passionate about- it’s just an easy thing to say so they don’t need to waste time answering questions. This makes it about YOU and YOUR passion. No one cares about you and its never about you- it is about others. The sooner you figure this out the better. Providing something that OTHERS NEED will make you a success faster and it is easy to become passionate afterward. No accounting grad is ever passionate about accounting. If they get their face plastered on a fleet of vehicles and have a lead accounting role at a huge company its easier to tell people he followed his passion, rather than he followed the money. I forgot who said this but money is a neutral indicator of value, by aiming to make it, you are aiming to become more valuable.
  2. Most people follow trends. Our feed is entirely #Blockchain and #Bitcoin, should our next million be in Blockchain? Of course not, dicky dee explains: “it makes it a lot harder to achieve your goals if thousands of other businesses are doing the same thing as you, it would work however if you have a solid way of differentiating yourself from the pack that would be highly advantageous.” Ease of entry is how he describes this “winner takes all” reality we live in where few players enjoy the bulk of the work. Do something no one else thinks of doing. How can you think like this? UNDER-CONSUME so you don’t need to work. Then instead of working, you can think. Most people don’t think anymore- they are constantly doing something, when they aren’t working/driving/yapping, they glance at their phone. Learn to do nothing but think, if you are bored that just means you are boring.
  3. Most people don’t talk about scale and instead focus on operating margins and net worth. Scale trumps margins. If you have scale, margins can decrease and as long as its positive you have a real business. Scaling is not linear and with the right skill set and framework you can go from half a million dollars in debt to “rich” in a couple years.  Read our customer’s great example in the comments section. Scale is relative and can serve anyone to some extent: why have one noodle house when you can have seven? *wink*  “Scaling with using minimal cash flow” is just plain efficiency. Most people are saving $1,000 a year on switching accountants, scarcity mindset tries to protect their net worth. Your net-worth is irrelevant when you are old, asset rich and cash poor. Cash Rules Everything Around Me: seek to maximize your company cash flow, you can spend as much as you want since your net-worth becomes meaningless after you realize having stuff is overrated.
  4. Most people trade their limited time for money. You can never get back time, so with each year of life you live, the marginal “worseness” increases. The piper will be paid, make use of your time now, so you are not wasting exponentially more time in the future. Only trade time for money when you have no money and lots of time on the money-time continuum. With each surplus dollar, you should trade money for time: someone is buying your time every time you look at their advertisement. You can buy time by outsourcing your bookkeeping/accounting. “If your business depends on you to be there instead of hiring out and creating systems and processes then you will never have true wealth no matter how much money you make because you don’t own your TIME and your income is capped off by how many hours you put in.” Leveraging technology has its limitation so how much do you pay someone to replace you? The most sustainable solution is that if you pay someone $20 per hour, they should also “pay you” $20 per hour. If you pay them $20 per hour and they “pay you” $40 per hour you should pay them more or you’ll lose them. And unnecessarily re-doing the hiring process at no gain is an enormous waste of time.

SwissBooks Pro Tip:

“Man muss immer umkehren” is a German saying that the solution to a problem can be clarified by re-expressing it in inverse form. Work backward and reverse engineer your target. A worthwhile target is to clear $1+ million in a year, if not through recurring revenue then at least through selling your business. The latter part is easier so you only need to generate between $200,000 to $333,333 in annual discretionary cash flow to sell your business for a $1 million. But by the time you are hitting those figures, you won’t want to sell anyway since you would have figured out how to scale.

An oversimplified example in online sales would be: you would need 100,000 sales at $10 of profit per sale. Assuming a 2% conversion this would require 5 million visitors, which will cost $500,000. So you need to come up with $550,000 (50K extra to live assuming 1-year cycle).

If you don’t have it – the process continues. You’ll need 55,000 customers in the preceding cycle at $10 profit per sale which assuming the same 2% conversion would require 2.75 million visitors, which will cost $275K. You need to come up with $325,000 (50K to live).

Getting this requires 32,500 sales at $10/sale with 1.625 million visitors which costs $162,500. You’ll need $212,500 (50K to live).

21,250 sales from 1.0625 million visitors costing $106,250. Requires $156,250.

781,250 visits costs $78,125. So if you had $50,000 of startup cash you could make this model work for you in 5 years and the only way to speed it up is by improving your margins or conversion rate, just don’t forget what is important (in this example its volume). Traps: If the cost of producing and delivering your offering is 50% of your revenue – its probably not worth pursuing.

9 Things You Didn’t Know About Christian Thut

  1. He hasn’t owned a cellphone in 10 years.

  2. He has never owned any Apple products or shopped at Walmart.

  3. He makes an effort not to consume popular culture. He considers this one of his “keys to success”.

  4. He is an expert martial artist. He got his black belt in Tae Kwon Do as a kid and trained Yan Yaw (Dance of Death) kick boxing in Asia.

  5. He has lived in 3 continents in his life.

  6. At one point he had half a million in debt. All his accounts have been cleared since 2015. He has written about how he got out of that here: Buying a home

  7. As of July 2017, he can bench press 300 lbs.

  8. He does not consume any products with soy or vegetable oils.

  9. He doesn’t have a microwave, use plastic containers/saran wrap or buy soap/bodywash/shampoo/deodorant.

We’ve received requests for a summary of our Facebook posts for those who are not on Facebook:

Most people will buy a house based on what the bank approves them for and will spend the better years of their life paying it off instead of following these metrics: Buying a home. As with everything typical, typical advice tailored to a typical person should be avoided if you don’t want to end up— well typical.  Keep it simple and still be better than the rest:

Two people graduate with the same degree/apprenticeship. Person A works the average 8 hours/day. Person B works 12 hours/day (focused).

After 4 years, Person A will have worked 8,000 hours and Person B, 12,000 hours = 4,000 more than Person A. Person B will have more $, more experience, ahead of Person A and will NOT be average.



“All activities consume the same limited time and attention. If you service low-impact activities, you’re taking away time and attention you could be spending on higher-impact activities. And because your time returns substantially more rewards when invested in high-impact activities than when invested in low-impact activities, the more of it you shift to the latter, the lower your overall benefit.”

-Cal Newport, DEEP WORK



Customers hand us money because at the cost of just 1% or less we reduce their total taxes by 3%-20%. But most people have a scarcity mindset, and will want to save $1,000 a year in accounting fees only to waste tens of thousands of dollars more.  Hence, our service is niche – focused on profitable businesses. If you plan on being average -SwissBooks not helpful and its not fair to recommend a product that is not going to be tailored to your needs.

Selectively choosing the people you surround yourself with is essential. 80% of your problems can be attributed to 20% of your customers.  Busyness and exhaustion are your enemy.  All regrets in life involve wasted time. This is the only thing you can never get back so never waste a second on marginal returns, short-term gains and people with no value. We have no sympathy for those who created their own mess. Poor choices reveal poor character. This eliminates the empty work that plagues all other accounting firms and allows us to focus on what really matters. Its amazing how our customer service improved when we focus only on people that like us.  Not a big deal, just not the same interests.   We don’t have a problem with your choice – we just don’t cater to everyone’s needs.

Catering to all businesses is a horrendous waste of time and frustrating by definition- all energy is wasted. Help people who have the potential to improve – they must make at least as much as they would through a regular job– otherwise they should focus on sales or a career. Without the “career capital,” props to Cal Newport, to support your business it will just be a downward spiral and 100x harder to fix.

Blogs like this free and leave people with no excuse for failure. If you were born here and are in your 30s, you are young enough to have access to the internet, and old enough to have the time to turn it around if you had some hiccups along the way. Just because you wasted your life does not give you the right to waste our time. You don’t want our advice, you want us to validate your stupid decisions.








No more posts?

We are going to up-date this blog less and less as you have all the information you need to succeed, we have dedicated that extra time to our valued clients instead. We had back-to-back 6-figure months – so we don’t have much else to say, too many accountants and *gurus* have too much to say – there is a lesson in that.  Everything you need to create a successful life is in this book:

Don’t Swallow Fluoride to Reap its Benefits

Many of us don’t know much about fluoride except that it is supposed to be good for your teeth and reduce cavities but there is so much I didn’t know. 

As quoted from Nassim Taleb’s Anti-Fragile (Chapter 21. Medicine, Convexity, and Opacity) “The non-natural needs to prove its benefits, not the natural—according to the statistical principle outlined earlier that nature is to be considered much less of a sucker than humans. In a complex domain, only time—a long time—is evidence.”

Just like the insecticide, DDT, discovered by a Swiss chemist (who actually won a Nobel Award for it), cigarettes, plastic, & cellphones were “harmless” until it all proved to be harmful after a long period of time. Or years ago, scientists came to the conclusion that cholesterol in food was bad = eggs were bad. Now, decades later, we find out the effect of egg consumption on blood cholesterol is minimal when compared with the effect of trans fats and saturated fats and according to a study at the University of Connecticut the fat in egg yolks actually helps to reduce LDL (“bad” cholesterol).

The approved 1.00ppm of fluoride in drinking water now MIGHT be harmful after another decade of studies.

If studies now show that it does affect IQ and other things then I’m going to do my best to avoid it in water where we cannot control how much fluoride we take as we need to drink a lot of water to keep healthy. There is already fluoride in some of the foods we eat/drink, & toothpaste. Other countries have access to fluoridated salt (ie. Switzerland) where the fluoride intake can be controlled for EACH individual. A smaller child can use less salt vs. an adult <— this makes much more sense than FORCING every single person to take fluoride through their drinking water.

  1. US National Library of Medicine National Institutes of Health: Critical Review of Physiological Effects of Ingested Fluoride as a Public Health Intervention (“CONCLUSIONS: The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.”)
  2. Department of Environmental Health, Harvard School of Public Health: Developmental fluoride neurotoxicity: a systematic review and meta-analysis  

    (“RESULTS: The standardized weighted mean difference in IQ score between exposed and reference populations was -0.45 (95% confidence interval: -0.56, -0.35) using a random-effects model. Thus, children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas. Subgroup and sensitivity analyses also indicated inverse associations, although the substantial heterogeneity did not appear to decrease.

    CONCLUSIONS: The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.”)

  3. Translated research report Fluoride 41(2) 115-119 April-June 2008 – Effects of the level of fluoride in drinking water on the intellectual ability of school-age children
  4. Fluoride news & lawsuit

So then I looked into Edmonton’s water: 2017 YTD median of fluoride in Edmonton’s water is 0.68 ppm!! Whereas most developed countries, including 97% of the western European population (Switzerland included), do not consume fluoridated water. 

After learning this we decided we had to switch our Mavea water pitcher out for something that could remove fluoride and found two products: Berkey and Zero Water. Pictured below is the Berkey which we thought was right for our family. 


The Berkey system effectively removes harmful viruses, bacteria, parasites and unhealthy contaminants from water and leaves essential minerals that your need. It purifies tap water & raw untreated water from sources such as remote lakes and streams.  It is SOOO good that they even recommend you to test your system after setting it up by putting water and RED FOOD coloring into the tank and the water that comes out is clear. The system which includes 2 Black filters and 2 F-2 filters cost us $351 plus we purchased an extra set of each filter so that it filters faster. After the water is filtered I empty the system into glass bottles and put them in the fridge (the system is BPA free but we avoid keeping food/drinks in plastic whenever possible). Use it at home, at the cottage, on a camping trip, or at your office/shop for clean water. I also recommended it to my parents for when they go back to Vietnam for vacation (who knows how clean the bottled water actually is!?)

Below are the cost in cents per litre of water filtered for both systems after 12 years: Berkey 0.0403 cents/litre (Amazon)  and Zero 0.1188/litre (Costco) and Zero 0.1387/litre (Amazon)  [The break even point is 2 years]

Here are the links to Amazon or Costco for those that have memberships at Costco for the Zero system:

Zero Water 10 cup pitcher Amazon $39.48 or Costco $64 

Zero Filters: Costco 4 filters for $70 or Costco 8 filters for $119 or Amazon 2 filters for $33  or Amazon 4 for $82.69 or Amazon 8 filters for $142.35

Below is more calculations I did for our family. The Institute of Medicine determined that an adequate intake (AI) of water for my family would be:

2.36 litres (1.18 litres/day for 4- 8 year olds & I have a 3 year old and 5 year old 1.18 x 2 = 2.36)
3 litres for men per day
2.2 litres for women per day
7.56 litres / day of drinking water for my family + extra water is required for cooking

The Berkey Light has a capacity of 10.4 litres so I would need to refill the system once a day for drinking and cooking. Using that I calculated how long my filters would last my family:

Berkey Black filter set purifies approximately 22,000 litres so 22,000 L / 10.4 L = 2,115.38 / 365 days = 5.8 years (5 years and 9.6 months) !! I purchased an extra set of Black filters so I have 2 sets of black filters = 5.8 x 2 = 11.6 (11 years and 7.2 months)

PF-2 Fluoride & Arsenic Reduction Filters is recommended to be replaced after 3,785 litres so 3,785 L / 10.4 L = 363.94 which is almost a full year! I purchased an extra set so I have 2 sets of PF-2 filters = 363.94 days x 2 or basically, 2 years.

Meaning I would need to buy around 5 extra sets of the PF-2 filters because of the life expectancy difference = $66 x 5 = $330

$351 system w/ 1 set of black filters and 1 set of PF-2 filters
$205 additional 1 set of black filters and 1 set of PF-2 filters
$330 additional 5 sets of PF-2 filters for the 10 year difference between the black filters and PF-2 filters
$886 / 11.6 years = $76.38 / year in clean fluoride free water!

As that includes the system the calculation below is for the NEXT 11.6 years of clean fluoride free water

$390 for 2 sets of black filters and 2 sets of PF-2 filters (11.6 years & 2 years)
$330 additional 5 sets of PF-2 filters for the 10 year difference between the black filters and PF-2 filters (10 years)
$720 / 11.6 years = $62.07 / year in clean fluoride free water!

REMEMBER! The number of PF-2 filters MUST match the number of Black filters to work as the PF-2 filters attach to the Black filters.

The PF-2 filters remove:

  • Arsenic V and peroxidized Arsenic III

  • Targets entire family of arsenic oxide anions as well as the arsenic cations

  • Other residual heavy metal ions

WARNING: huge list below these 2 photos of what the Black Berkey filters remove!!
