As I mentioned a while ago, I wanted to be a gamedev; after going back and trying it for a bit, there are certain aspects to it that I find I am good at, certain aspects I am not, and the latter is part of the problem.
Still, the other thing I always wanted to be was a writer. (Not necessarily an author, the two have some differences, mostly in what gets written and who the audience is.) And I've been working on that, been at a few short-story competitions, the last one I entered I didn't place, per se, but I did get an honourable mention from the judges.
