Find something to do and keep doing it until you drop dead; period.
While sitting in my room, I decided to watch myself do something on video. Unsatisfied with the turnout, I then realized that I must be crazy for doing what I'm watching myself do. I then turned the video off and later turned it back on and said to myself, "I don't care what other people think, I'm going to keep doing what I'm doing anyway. Eventually I'll get it right."
