Music, Books, airplanes, writing, movies, politics. Being with friends, getting things done, music equipment, eBay, Milo, Virginia, building and riding bikes, going to shows, vegetarian/vegan food, recycling, biodiesel and other such hippy crap, punk rock, history, etc., etc. I've been addicted to celebrity gossip websites for three years and am probably stupider for doing so but I don't really give a damn. I have many...books...by authors like Proust and stuff so that should make up for it.
Laughter. Wonderful People. Recently I think I met Adulthood, but I could be wrong. He was wearing a hat.
If it came out before 1990, involves bass, guitar, drums, and didn't get radio play then I probably dig it. I like stuff with an inventive and pulsing beat. I like music with raw emotion, not put-on and trite crap. If it frequently gets represented on a t-shirt in a gaudy over-the-top florescent and barely-readable font then I probably loathe it. Originality is a must (in all things really, but particularly in music). Lately it's been, but not limited to, lots of this stuff:
Superbad, Supertroopers, High Fidelity, Forrest Gump, Slackers, Dogma, etc. etc.
The Office and South Park are really all I care about. I like Arrested Development on DVD too, as well as Aquateen.
Bukowski, Camus, Steinbeck, Hemingway, Dostoevsky, Twain. Nonfiction and Hunter S. Thompson, too. Still need to get around to reading that Potter stuff.
My parents, my grandparents. Lots of other people.
