@badusername715,
Depends on you I guess? I like playing Magic The Gathering, it's a hobby that many consider expensive, but there are ways to play for free, but I can also go to the store on friday nights and play with other people. Also just online games in general. If you're looking for excitement to be more social or something, you could just take a walk around where you live and see what there is to do. That's how I found a hiking trail I never knew existed, and it was actually fairly populated by the locals. If you're looking for a potential love interest, get a coffee and go to the park and try to strike up a conversation. Just, don't approach a girl who has a guy standing right next to her.
Also, if you're not looking for love, just start up some hobby, play an instrument, taking up karate, yoga, whatever.
