I recently hit a major financial goal and it's been a big psychological boost - I know now that I can achieve such goals if I work at it and suddenly everything is open. Volunteering with the SPCA and looking into the local astronomical society. I am registered with sacgeeks.com but I never go to any of the events.
I'm usually happy with a big dumb action movie, an occasional elitist drink, and good company. If the movie has a raging metal soundtrack, it's like my own little Nirvana.
