I would add that there's a pushy little schlemiel who lives inside my brain who won't leave me alone until I express in one medium or another whatever idea or dream he wants to let fly. He's apt to start stomping around in the middle of the night, or at a time when I really should be doing some income-producing work, or whenever he gets a notion. He's a real slavedriver too--won't leave me alone until the project is done, even if it entails a handful of months or years.

I'm going to take a wild guess that some others here have his siblings bothering them.
