Listening to music can most usually make me happy, but I have to be already kind of happy for this.
Being happy is something I hold very important, because if you're not happy, you might as well be dead, 0 is better than -3.
Anyways, lots of stuff besides music makes me happy. MAKING music makes me very happy, especially when it's just a jam that turns into a really nice song, rather than a carefully thought out and constructed song, I just enjoy when I start playing, then other people do. And it's like "Hey start playing the harmonica along to this" etc. etc. and it just is on and works, so nice.
This is kind of dumb, but smoking pot with friends makes me really happy, it's just fun to lose your mind and act like an idiot with people every once in a while.
Lately what's made me most happy is talking to someone I really care for online, although it makes me sad that I can only talk to her online. Overall from that though, more happy than anything.
Drawing makes me happy as well, when I think of something cool to draw, I love to just clear my desk and start drawing it, not stopping until I finish, then when I finally do finish it's tempting to just keep adding more and more details because I don't want to stop drawing it
I also enjoy seeing other people being happy or enjoying themselves. Two girls in my mathclass would always joke to each other with these inside jokes and just crack up hysterically, I couldn't help but feel happy from them feeling happy all the time.
UM makes me really happy (obviously), there's nothing like a place where you actually like more people than you dislike (as opposed to the real world). People here are for the most part very open-minded, intelligent, friendly, sweet, and caring. I couldn't ask for better people to talk to and joke around with.
Money really doesn't make me happy, I would rather just be around people I love than be loaded with money. I'm sure it would be fun to travel and buy a bunch of CD's and nice amps etc. etc. I would probably enjoy myself, but I don't think i'd actually be happy from money. Happiness doesn't come from material crap, not the happiness I want at least.
I'll add more later, I know this is probably long enough that half of the people will skip reading it
(I'm guilty of this quite often)
