I think too much. When I set out to do something creative like writing, I think about it way too much before I really start, and before I know it I've tried so hard to be professional about it that I've forgotten to just write. This time I've decided I'm going to let professionalism come with practice, rather than from sheer force of will from the outset.
So... I don't really feel like a writer. But sometimes I feel like I want to be. So I'm just going to, and I'm going to see where it goes.
