Whenever I need inspiration, I watch Seinfeld. The way they can make every simple, every-day sort of thing become funny inspires me to look at the world and smile (on the inside, I’m against public smiling).
Another great inspiration for me is Rod Stewart. The guy can’t stick to a note, and he’s got the voice that whenever you see him get near a microphone you should run away. But in spite of having little singing talent (in my opinion anyway), he became a huge star in his day and still rocks on at an old age. So that inspires me, because it shows how even without great skills or talent, if you believe in yourself you can really do anything… whether you should do it or not is a whole other story.
I realize these aren’t really writers… I don’t really have any special inspirational book. I like reading anything and everything… and I can always write stuff, whether I’m inspired or not.
