The following is from a post by Chase Jarvis of critical keys to success. This was the first, and for me, the most damning.
1. Get shit done.
Over-thinking, pontificating, and wondering are tools for the slacker. People don’t care what almost happened, or what your problems are or why something wasn’t. They care about what is, and what will be. That requires actually making stuff happen. Pros do, make, ship, send, publish, post and deliver; amateurs sit around and wonder, or worse, scratch their arse.
