Write more

Was chatting with a pro comic the other night and I asked him what he knows now that he wishes he knew when he was starting out. His answer: Write more. "There's nothing I'm writing now that I didn't have the insight and knowledge to write ten years ago. I just didn't work hard enough at it then." What about having to deal with a day job? "There's always time." Does that feeling go away? "I always feel I should have another hour of material more than I do."
