Listen to bad shit, watch people do stupid shit, listen to some guy talk about how he knows so much except that he's still just a dumb fuck.
The only way I got past caring about fucking up was by watching other people fuck up and then fucking up.
There's some improvement of skills somewhere in there based on "what not to do", but I think I just got caught up laughing at myself too much.
Have this piece of shit to maybe make you feel better about your own work, and improve based on what you don't like about it.
