I used to have tons of hobbies, then they all got too expensive lol. There's still lots of things I do to pass the time though...
Learning about all aspects of computers. In fact, I'm attending classes that will hopefully expand my knowledge of them greatly.
Playing instruments, but mainly only guitar these days. I used to be a drummer in a band, until I had to pay some bills, then the drums had to go bye bye.
Working on vintage and classic vehicles, true vehicles that ran on gas and mechanics, not electricity and computers. Ironic, huh?
Daydreaming constantly of what the world would be like if it were full of anthros instead of self centered, greedy humans.
Partying when I have the time and/or money to do so. Can't have all work and no play. Getting drunk is ok as long as nobody drives.
Eating!!! I love eating, and trying new foods whenever I have the chance. I'll try anything at least once.
I used to be a big-time gamer, but I no longer have any gaming consoles, and have gotten so far behind on new games that I doubt I'll ever catch up.
Painting is relaxing, but I'm talking like painting a house or a car...one solid color. I'm a terrible artist, so there's no chance I'd ever make any art, but I like to see the differences that different colors make.
There's lots of other stuff too, but most of it is too boring to post lol. TV and movies and the likes.
