This is my new favorite thing right at this moment:
"Heed the words of Robert Frost. Start with a big, fat, lump in your throat, start with a profound sense of wrong, a deep homesickness, or a crazy lovesickness, and run with it. If you imagine less, less will be what you undoubtedly deserve. Do what you love, and don't stop until you get what you love. Work as hard as you can , imagine immensities, don't compromise, and don't waste time. Start now, not two weeks from now. Now."
It's from an amazing talk Debbie Millman gave.

I hope you find something in there to help get you unstuck.
Keep writing. It saves lives.
