You do start to get a false feeling of invincibility after being validated so much in your actual field (even if it is largely due to being in the right place at the right time). Most one-hit wonders who manage to hit a homerun in the Valley with their web app who then end up trying to solve world hunger, etc. afterwards fail. I do have to hand it to Gates though (but he isn't a one-hit wonder).
Gates has the good sense of surrounding himself with deep expertise in everything he takes on.
He was smart to avoid the typical tech guy hiring only a bunch of other tech guys to try and take on problems like hunger, global health, and education.
