Join Facebook even if it scares the living hell out of you. Keep in touch with your lit gang. Make some new lit and non-lit friends. Let people into your writing life. It makes it less lonely.
I did it because I didn’t just want to be someone with an MFA, I wanted to be someone with a shelf of books and short stories and screenplays with my name on them. The fact is you will be much grumpier if you don’t write than if you do. You’ll feel better after you’ve written.
