Trading and speculation can make money, not because the personality has no flaws, but because it has huge flaws. Anyone who makes big money from trading is not a normal person.

Individuals with exceptional abilities are never normal; either they have a temper that confuses others, or they are as cold as ice, or they are so paranoid that even nine bulls couldn't move them...
In short, there is always one or two aspects of them that seem to be super incompatible with the people around them.

What does it mean to be normal? Normal means being like most people. Most people are poor. If you're normal, aren't you just as poor as most people?

The so-called normal is essentially a synonym for mediocrity. In psychology and behavioral science, there is a term called conformity, meaning that most people, for a sense of security, will naturally smooth out their edges to fit in. But those who truly have great abilities have long ignored this meaningless social drain; they don't need to conform.

The weirdest person around is often the one who gets the results the most ruthlessly.
