Misfortune begins with comparison

"Making a lot of money - that's what I call being a symbol of the intelligence."

I believed so when I was young.

When I was 24 or 25 years old, I realized that I have nothing to do with the feeling of happiness even if I compete with something and win it. In other words, I never have a happy life unless I stop comparing myself with others.

Furthermore, if I express it in other words, we investors don't have to care so much about comparing our performance between reference index (example:S&P500).
