This thread made me realize I need some hobbies
Dude the older you get the more you need them. Otherwise you will be woefully disappointed in life, as your friends family and coworkers start to piss you off more and more.
For me it's playing, singing, and writing music. It's kinda been my thing for over 10 years.
I'm also trying pretty hard to pick up a little bit of german, and possibly portuguese/hindi.
Also added to the list in the last little while is my desire to pick up a competitive team sport.
And finally I try really fucking hard to be a knowitall. It's serious business bit of a pain in the ass once you realize most people can't be bothered to pick up/respect basic things like geography.
