Acting, Salsa, rock climbing, guitar, roller blading, the didgeridoo, drums, alcohol, women, food, good books, and a never ending supply of good music.
People who like me.
Radiohead, BT, Led Zeppelin, Sublime, Pink Floyd, Paul Simon, Jane's Addiction, some hip-hop, Salsa/Latin, Coldplay, Sigur Ros, Paul Van Dyk, Paul Oakenfold, and just about everything else except country.
Too damn many to bother listing. But some of the top are: Fight Club, Heat, Dead Poet's Society, Closer, Scarface, Godfather parts I and II, Amelie, Das Boot, Y Tu Mama Tambien... etc etc
Siddhartha, Still Life with Woodpecker, Small Gods, anything by Dan Brown, The Chronicles of Narnia, Lord of the Rings, Atlast Shrugged and the Fountainhead, Harry Potter, Steven King's Dark Tower series, and epic climbing non-fiction like "Into Thin Air" and "Shackleton's Adventure". Those guys are badasses. The poetry of Pablo Naruda and the philosophy of Eckhart Tolle.
Not heroes, but actors I admire and aspire to: Edward Norton, Matt Damon, Jude Law, Al Pacino, Brad Pitt, and for the fun stuff - Ben Stiller, Owen and Luke Wilson, Vince Vaugn (as of late), and Robin Williams.
