Experience with an audience. Also like I'm sure with Bus it's the same thing, I used to sit in these joints and you know, you're playing with people all the time who are better than you are. And that's the only way to learn it. You go, like, if you're the best kid in the band, then you're in trouble because there's nobody to learn from. You should always try to play with people who are better than you are, so that some of that rubs off on you hopefully.
