I agonize over the first sentence, then the first word, and never get anything done.
Or if I start in the middle, or somehow end up there anyway, I write half a sentence, forget what I'm doing, then sit there for ten to twentr minutes and "try" to "remember" what I'm doing by doing something else.
As for creative thoughts in general, I SOMETIMES write down what great idea I thought of, and usually never get interested enough again to expand on it.
Sometimes I do, though. That's when THIS happens:
