"Investing is an intellectual game." I didn't quite understand this before. Buffett said that the joy of investing comes from the game itself, not from how much money you make.

But through recent in-depth research, I’ve also begun to feel a different kind of happiness—one that’s not the short-term pleasure of "immediate profit," but an intellectual delight.
It depends on knowing how much I will earn, and when, and in which field I will earn it—that’s very interesting.
I always approach each field with the goal of becoming a top expert. What could be more satisfying than that?
Most of the time, I stay humble, but the pride and arrogance inside me remain the underlying tone—sigh, when I was 10, my grandfather complained to my mother that I was so proud it was annoying.
Many years have passed, and now, on this morning, I once again proudly declare, which is also quite interesting.
