Is it talent tough or some stuff from earlier in life? Some basics missed?
“I tend to think of social norms as contracts bargained between different groups. In the case of attitudes towards intelligence, those two groups are smart people and dumb people. Since I was both at once, I got to make the bargain with myself, which simplified the bargaining process immensely. The deal I came up with was that I wasn’t going to beat myself up over the areas I was bad at, but I also didn’t get to become too cocky about the areas I was good at. It was all genetic luck of the draw either way. In the meantime, I would try to press as hard as I could to exploit my strengths and cover up my deficiencies. So far I’ve found this to be a really healthy way of treating myself, and it’s the way I try to treat others as well.”
