Just go out and shoot, shoot, shoot!
This one drives me pretty wild, too. Somehow, there's a myth that if you can just get the first 10,000 frames out of the way as fast as possible, you'll start being good.
Not that I oppose shooting a lot, there's really no getting around the fact that almost everyone has to fail a lot before they can succeed. Recognizing that you're going to have to play a lot of tennis to get any good is rational thinking; simply going out and swinging a tennis racket around blindly for 10,000 strokes is not.
By all means, shoot, shoot, shoot. But do so with purpose, press the shutter release with an idea in mind, and look at the result with the same idea in mind.
I'll have more to say on this, and some counter-advice if you will, in the next few days.
