A reader of the column recommended the book, "Fooled by Randomness" -- which is interesting.

I think the introduction's sentence, "Why do people think it's their own ability when they make a profit on an investment and think it's bad luck when they lose money?" in the introduction.

I have "used" or rather "abused" the "Monte Carlo method" frequently mentioned in this book.

It is really easy to get a quick probability value answer with a simple program rather than a complicated formula.

I used to use the Monte Carlo method all the time in my columns around here, and it was really useful.

(A reader has since successfully formulated it.)

Aside from that.

As a mathematical analysis engineer, it is common sense to me to say, 'If you start playing the game, you lose at that point.

It seems to me that I have done too many calculations in the past to believe that I am the only one who can win.

I have lived a life of "if you don't play the game, you won't lose" which has enabled me to read books, write columns, do programming, and eat rice.

I think this is quite a 'win' -- although not very noticeable.

Oh, I would like to take this opportunity to report on the progress.

"Random Walkers on Wall Street" Barton Malkiel -> Unread

"Learn to Earn" Peter Lynch, -> unread

Fast & Slow" Daniel Kahneman → read

"Fooled by Randomness" Nicholas Taleb -> read

"Black Swan" Nicholas Taleb → read

"Moneyball" Michael Lewis → read

"Flash Boys" Michael Lewis →read

In particular, "Flash Boys" is a highly praised book by Ebata that I can't tell you how many times I've read it.

# I was dazzled by how bad the story of the film adaptation was (really, that was a waste of time).

Anyway, after reading "Flash Boys," I understood on a soul level that "ordinary people trading are just going to get eaten alive.

In my current series, "The Engineer who is not loved by money", I have only 'index investing' as an option.

Well, I'll get back to this story at some point.
