Story of Neighbours – Janitor Lottery Man

To begin the idea of
randomness, I will recall a short story written in the book.

Consider two
neighbours, John Doe A, a janitor who won the New Jersey lottery and moved to a
wealthy neighbourhood, compared to John Doe B, his next-door neighbour of more
modest condition who has been drilling teeth eight hours a day over the past 35
years – A Dentist.

Clearly one can say
that, thanks to the dullness of his career, if John Doe B had to relive his
life a few thousand times since graduation from dental school, the range of
possible outcomes would be rather narrow (assuming he is properly insured).

At the best, he would
end up drilling the rich teeth of the New York Park Avenue residents, while the
worst would show him drilling those of some semi-deserted town full of trailers
in the Catskills.

As to John Doe A, if he
had to relive his life a million times, almost all of them would see him
performing janitorial activities (and spending endless dollars on fruitless
lottery tickets), and one in a million would see him winning the New Jersey
lottery.

Even if you win 99
times out of 100, there is no certainty that you are successful. Your one

There are routes to success that are
non-random. Those who go the extra mile are rewarded. In my profession one may
own a security that benefits from lower market prices, but may not react at all
until some critical point. Most people give up before the rewards.

Time Eliminates
Randomness

Nassim believes that success can be attributed to luck
because of a lucky sample path or a rare event. Only over long time we can see
true capabilities. Time aggregation eliminates effects of randomness.

Stop loss, a predetermined exit point, a protection

against the black swan. It seems like it is rarely practiced.
Nassim described Nero as a trader who is very risk averse.
“Nero rapidly exits
trades after a predetermined loss. He
never puts himself in a situation where he can lose more than, say, $1,000,000
– regardless of the probability of such an event. That amount has always
been variable; it depends on his accumulated profits for the year.

never puts himself in a situation where he can lose more than, say, $1,000,000
– regardless of the probability of such an event. That amount has always
been variable; it depends on his accumulated profits for the year.
Nero’s temperament is
such that he does not mind losing small money. “I love taking small
losses”, he says. “I just need my winners to be large”. In no
circumstances does he want to be exposed to those rare events, like panics and
sudden crashes that wipe a trader out in a flash. To the contrary, he wants to
benefit from them.

benefit from them.
Why doesn’t Nero make more money? Because of
his trading style – or perhaps his personality. Nero’s objective is not to
maximize his profits, so much as it is to avoid having this entertaining money
machine called trading taken away from him. Blowing up would mean returning to
the tedium of the university or the non-trading life.

machine called trading taken away from him. Blowing up would mean returning to
the tedium of the university or the non-trading life.
Every time his risks increase, he conjures up
the image of the quiet hallway at the university, the long mornings at his desk
spent in revising a paper, kept awake by bad coffee. No, he does not want to
have to face the solemn university library where he was bored to tears. “I
am shooting for longevity”, he is wont to say.”

History & Probability – Irrelevant
Historical event and frequency of probability is totally
irrelevant for event of success. It needs to be judged in connection with the
magnitude of outcome. E.g. Event A: 999/1000 chance of winning $1 and Event B: 1/1000
chance of losing $10k. Will you bet?

“On the rare occasions when I boarded the 6:42 train to New York
I observed with amazement the hordes of depressed business commuters (who
seemed to have preferred to be elsewhere) studiously buried in the Wall Street
Journal, apprised of the minutiae of companies that, at the time of writing,
are probably out of business. Indeed it is difficult to ascertain whether they
seem depressed because they are reading the newspaper, or if depressive people
tend to read the newspaper, or if people who are living outside their genetic
habitat both read the newspaper and look sleepy and depressed.”

Studies
have shown that we feel the effects of negative emotions 2.25 times stronger
than we feel the effects of positive emotions. Therefore if we view an
investment portfolio every minute of the day, the mere randomness factor of the
markets will cause us to feel more pain than positive emotions, even if our
portfolio has increased in value.

Wealth – Do Not Compare
When there are too many millionaires next door, you are often
a failure, a very successful but comparative failure. Therefore move away from
your house / neighbourhood.

I don’t buy options. Buying options is another way to go to the

Visibly,
the statistic that 90% of all option positions lost money is meaningless,
(i.e., the frequency) if we do not take into account how much money is made on
average during the remaining 10%. If we make 50 times our bet on average when
the option is in the money, then I can safely make the statement that buying
options is another way to go to the palazzo rather than the poorhouse.”

Clearly, I am amazed by
how one topic of “Randomness” can lead to an Author write a whole book.

I am actually further humbled
after finished reading the book. I very much agreed that a random event of luck
is critical to being successful, i.e. if success is very much related to
wealth. And the time factor is not a critical consideration.

continue to improve ourselves, have good attitude, positive mindset..etc.”

Hi Rolf,

Hold on to that idea and go on to read black swan. The picture becomes clearer and the idea gets crystallized when you finish the trilogy (fooled by randomness, black swan, antifragile …in that order). If you still have time, throw in bed of procrustes.
He is still my favourite modern day philosopher 😉
Hi LP,
Thanks for the introduction. Really appreciate it.
Since young, I had always did poorly in my english. O Levels was a random event that I got B3 – I was ecstatic. During A Levels, it a better reflection when I got E8 for GP.
In this book, many occasions, I read the same paragraph several times to understand. another 3 books by Nassim Taleb….. phew… lots of my my time…..
Literature is also not my strong subject. You know Nassim Taleb loves poems.
Adam Khoo's books are still easier to read…haha…
Hi rolf,
Don't worry! Some books take more than 1 reading to appreciate, and it's often these books that we come back again again to revisit the ideas. The book might not have changed, but we will grow and interpret the same words different based on what we had experienced in life.
Just get a brief over view of the big picture. You don't have to understand every line in order to see the bigger picture. Black Swan should get better to read than this 😉
Hi LP,
Indeed. What is the same reads different over time! What is changed? Not the contents, but ourselves!
Must read black swan before the black swan.. thanks for the recommendation.
Buy ToTo. $3.8m on Monday and get lucky
Hi CW,
After Monday, I will have 3.8mil war-chest to whack….
Then I can have 6 figs of passive income.
I will sing "if I have 1 million every morning".
By the way, I have never buy Toto in my life. How to bet huh? hehe
It's a great book indeed. Fooled by randomness made me realise there's a lot of bullshit out there that we need to filter!
Hi RetailTrader,
Yes, we are born to filter. Look at our health systems, almost every system filter.
Nassim Taleb is a uniquely talented character!
Hi Rolf,
Thanks for introducing this book. I'm going to make that my next read. It reminds me of the book "freakonomics", was it really luck that a drop out like Bill Gates founded Microsoft and why is that Students born earlier in the year always seem to do better than those born near the end of the year.
Hi Derek,
The thanks belongs to LP. Enjoy the book.
Is it true that students born earlier in the year always seem to do better? Hmm..
Now I know the time to try for baby! 🙂
Hi Rolf,
I read this book before too, damn good. Gonna read again!
Hi Lazy Singaporean,
Great minds think alike! It's not a typical book, but one that is uniquely clever, and has its own flair!
By the way, thanks for dropping by!
I read this and its give us good idea how to success in school education and how win study competition thanks for sharing sample high school student resume .
