Music, guitars, art, world history, computer games, guns, + lotsa other stuff.
People, preferably friendly ones.
Too much to list, really.
Comedies, preferably, but I also enjoy a good action or drama flick.
I'm addicted to all those big TV series like LOST, Prison Break(first two seasons only), The Wire, The Shield, Desperate Housewives... Also, some good sit-coms, such as Seinfeld or Titus. The Simpsons and Futurama are also appreciated.
I'm not a dedicated reader of fiction, most of what I read is factual stuff rather than fictional.
There are people I look up to, but whether or not they are my heroes, that's not something I think about too often, really.
