2 quotes
The single most important thing, if you want to avoid a lot of stupid errors, is knowing where you’re competent and where you aren’t. Knowing the edge of your own competency. And that’s very hard to do because the human mind naturally tries to make you think you’re way smarter than you are.
A lot of smart people think they’re way smarter than they are, and therefore they do worse than dumb people. And it’s very common to be utterly brilliant and think you’re way the hell smarter than you are.
