There are different versions of “learning to think.”
Some people learn to kiss ass, and to fit in with rich people, and they call that “learning to think,” when it’s really, “learning to be a willing servant to anyone who has lots and lots of cash.”
This is not ordinary networking. This a a special kind of social skill.
When people advocate “learning to think,” they usually mean that skill.
However, I personally have my own ideas about learning to think.
I think that mathematical logic is the best way to think. The more high-level mathematical logic you can do, the better you are at thinking, according to me.
Of course, I recognize that great mathematicians often die broke or become recluses. I don’t claim that learning to think actually results in money.
