Keep at it!
I've been totally swamped with all kinds of good things (and even though they're things that make a person wake at 4 a.m. in an absolute panic, complete with heart palpitations, they're still good things, right?), but I wanted to post this great bit of advice from Get Out the Box by Ira Glass that a friend just sent me. Excellent advice for creative types like you.
The crux of it is this: don't give up. KEEP WORKING!
