Sit down. In the chair. Finish some stories. Submit them to the highest markets, and when they are rejected, go second-highest. Keep submitting. Or, don't--write some novels, if that's easier. Submit those, too. Stop wasting your time gaming. You know that other people are fulfilled from gaming, but you aren't, so get on it. Also, stop believing that just because you haven't done X, you're unqualified to get on with life. So, go. Seriously. Go now.
Dear Mer 2005:
If you don't WRITE, you won't get better. At this stage in the game, it's all about the PRACTICE. No amount of career navigatory planning is going to get you the practice. GET ON IT.
Dear Mer 2007:
Remember how all those authors said that you should enjoy your time before the deadlines hit? That is not something authors say because they're trying to make YOU feel better. They are JEALOUS AS HELL of you, that no one is going to yank your WIP out of your hands to turn around the galleys.
Don't get me wrong, I'm happy to be a working writer. But still. Time to call your own is precious.
