I've posted this quote several times over and over and I do it because it's a great reminder to me and to everyone who wants to do something. It takes a while to get good at something. Remember that you have the taste, so you just have to keep working at it and do more of it. If its bad, so what? What did you learn from it? Now go and do more and do better.
Bottom line, don't give up just because the end product doesn't turn out the way you think it should. The gap between your taste and your skill will eventually close. Keep on making!
