Good read from Inc Magazine.
One of the quotes:
"I always live by the motto of 'Ready, fire, aim.' I think if you spend too much time doing 'Ready, aim, aim, aim,' you're never going to see all the good things that would happen if you actually started doing it. I think business plans are interesting, but they have no real meaning, because you can't put in all the positive things that will occur...If you know intrinsically that this is possible, you just have to find out how to make it possible, which you can't do ahead of time."
