Writer's High

I'm coming down off the high that is an acceptance.  That's the thing about writing, it gives you these highs.  The other great high that writing gives you is that feeling you get when you've written something you know is good.  And even if it isn't really good, it's something you're very happy with.  I actually experienced both highs yesterday, maybe a banner day in my writing life.  So, question of the day is: what is your favorite writer's high?
