Check out "Zen and the Art of Motorcycle Maintenance". There's a section in the middle somewhere where Robert Pursig (the auther) is teaching a writing class and a girl approaches him with a 'stuckness' problem. I won't parphrase here, because it's been decades since I read it. But he givers her some great advice.

Then write a letter to someone. At least you'll be writing and it will have some purpose to it.
