Are you saying that painting isn't a part of "anything"? You were the one making a wild generalization. What about fighting in war, like Napoleon? In any case, the comparison is valid because like I said, fighters go through the same thing and the same psychology has been observed. It's not a fighting thing, or a painting thing, or a war thing, or a science thing. It's just the nature of humanity - they don't all approach challenges the same way, but there are multiple ways to get through a challenge. Fighters in the UFC are much more likely to act out because their bosses tell them to, though.
