If you have a thing people want that you spent a decade making that isn't easily replicatable, the rest doesn't matter.

If you don't have that, the rest also doesn't matter. Unless you're obsessed with money, in which case, you are very confused and should not be guiding anybody to anything.

Guides regarding minutiae from lottery ticket winners are tiresome. I think anyone over 30 has learned what these 'guides' amount to from looking at Paul Graham.
