Would you rather be amazing at something mediocre or mediocre at something amazing? An incredible typist or a moderate book author? The world's best Etch-a-Sketch artist or a so-so painter? Personally, I think we should aim to develop skills in the amazing category. Homing in on one everyday skill like sock-folding and becoming extraordinarily good at it might impress a few people for a few seconds, but the payoff is too small. Speaking economically about your days on Earth, you should spend them doing things that are worthwhile, and if you want to amaze people, the better payoff comes from developing skills in fields that people already think are amazing.
