What do YOU do when creativity dries up?

["BC" <compguy2@comcast.net>]

I'm sure this has been covered in the past before my time here. Perhaps it's 
a good thing to take a fresh look at the phenomenon and coping strategies 
from time to time.

What do you do when the creative flow diminishes into a creative drip and 
then seemingly dries up completely? You sit at your instrument to come up 
with some new ideas and......nothing!

You have a vague sense that your passion is just not there. You might even 
feel "cludgy" and awkward at the instrument. Aside from letting time pass, 
would anyone like to share their strategies for minimizing time spent in the 
creative desert?
