Lots of people have many different quirks and stuff, especially the kinds of things that people get excited over. So what excites you? I get happy about some pretty stupid stuff sometimes, like catching the subway RIGHT when I walk to the platform, or finding a movie on tv that I haven't seen for a long time RIGHT when it's starting. I also get strangely excited when I make a thread that becomes popular, or when I get a new rep or something. It's pretty dorky. Usually just getting positive comments about ANYTHING makes me a bit happy.
