I don't. I sit in the chair and start writing. Inspiration almost never fails to show up, but I have to start the party. As Chuck Close says, "Inspiration is for amateurs; the rest of us just show up and get to work." Now, all that kind of arrogant stuff being said, I get inspired by EVERYTHING. TV commercials, a song on the radio, something overheard in the grocery store - all of it makes me think, "Hmmm, that would make a good story..." You just always need to be in that frame of mind, and inspiration shows up constantly.
