自己
You have to figure out what your own aptitudes are. If you play games where other people have the aptitudes and you don’t, you’re going to lose. And that’s as close to certain as any prediction that you can make. You have to figure out where you’ve got an edge. And you’ve got to play within your own circle of competence.
I never allow myself to have an opinion on anything that I don’t know the other side’s argument better than they do.
Knowing what you don’t know is more useful than being brilliant.
