I know, kind of lame but seriously. I think GO is sometimes the most important aspect of writing. You just have to keep going, no matter what! Right!
If you feel rejected--Go write!
If you don't know what to write next--Go take a break!
If you're stumped-- Go read!
If you need sustenance--Go eat!
If you need a reward--Go shopping! ( Books or Chocolate)
If your back is cramped--Go do Yoga or take a walk.
You have a deadline looming--GET GOING!
What's your GO TO when you're writing?
