Music and art, among millions of other things.
The Dalai Lama
I listen to anything that makes the hair on the back of my neck stand up, whether that is the classical compositions of Bedrich Smetana or the amazing gray metal of Agalloch.
Currently listening to a lot of: Windmills By the Ocean, Across Tundras, Steve Von Till, Agalloch, Woven Hand
Movies that make you think, or knock you on (or off) your ass. I will watch and enjoy pretty much anything that comes on the classic movies channel.
I watched The Diving Bell and the Butterfly recently, and that is one of the best movies I've ever seen. Highly recommended.
Current Favorite movie: Apocalypse Now
Deadwood (mini-series), Dexter, Raines (a very short-lived show with Jeff Goldblum that no one has ever heard of, but was amazing), Monk, South Park, Frisky Dingo, Harvey Birdman, Flight of the Concords, anything on the Discovery or History Channel.
Anything written by Jack Kerouac or by someone who wants the world to change for the better, and tries to provide the only means they have to do so.
