Achievement. Setting a goal, especially those I thought was tasks for people other then me, and achieve it.
Music. Funny, I allso thought it was the biggest waste of time for a big time. But I knew this song which I loved so much when I was younger. But it could not be found downloaded nor bought. Untill one day, my parent inherited a piano. I sat down and slowly worked up with playing the melodie out of my head, soon finding out I could create my own versions or entirely new melodies like a touch of magic coming from nowhere. I still don't know playing from notes, but I can forget time and hunger completly sitting down creating a play of sounds.
Conquering fear. Wether it is talking to a stranger, jumping out of a plane or eating an entire can of tuna, it makes me feel so empowered. Like I could do anything.
Travelling. I can hardly talk to somebody not liking or wanting to travel. Seeing impossible creations of men, marvelous wonders of nature, new flavours of women or the entire social dynamics between sexes in different cultures, new activities... Makes me feel restless just thinking of it. I can't imagine how sad a life born, lived and died in the same city would be.
Surprising people. Work for many months on a skill in total secrecy, then one day throw it in the face of a close friend who think he has you figure completly figured out. I swear I'm willing to give my left testicle (the right one is my favorite to see the face of my friends when I first showed them a small symphony I made, or threw out some neat breakdance powermoves :).
