Perhaps this is the reason that Dungeons and Dragons DM advice is so detailed and exhaustive that it would take hours to prepare each session, while actual D&D games with very little DM prep are usually still fun. I got the "I must shoot 10,000 free throws to be prepared" attitude about becoming a developer -- must know Linux, concurrency, all interview questions, salary negotiation, and so on. It was daunting but ultimately correct, I got the kind of job I wanted and doubt I could have done it without being neurotic about it. Or maybe I would have been fine and I'm still being neurotic and overdoing it.
