What have you done lately?

Here I just wrote a screenplay in a week -- if one doesn't count the 25 years brooding about it! -- and still have the usual blahs that come after finishing something. It's hopeless. The fun is always in the doing, and the letdown always follows. And the letdown has nothing to do with disappointment or lack of pride in the work -- I still think I'm going to sell this mother. Somehow it's built into my creative psyche, so when I finish something, I feel like I should be doing something else immediately. And I'm not. Well, the vocal score, but that's a different animal. I'll tell you, not everything about the creative life is pleasant. But it's the only life I know.
