“When does the mastery end? How many things do I need to be good at to feel good about myself? Could Dan Brown really teach me how to write a thriller as well as he does? Do I even want to try? Or has the access to geniuses of various types simply made us feel bad that we aren't enough just being interested in what we're interested in and accomplishing the less-than-genius-level things we already accomplish? Do I need to be good at more things or simply find more enjoyment in what I'm already pretty good at?”
