I think most people are just not passion-developers. I know I'm not. There are people who seem to be very single track in some areas. They like one thing and they like that one thing. Often they liked it from a young age. And they don't care that much for various other things around them.

I was never like that, I was never single track. There are a lot of things I find interesting, but there's no particular thing that is so all-consuming it can eclipse everything else.

There is no good advice because building a society is not about giving individuals good advice, it's about building a good society that a variety of individuals can thrive in without following esoteric advice.
