I guess at this point coming to this site is my hobby.

Studying...

Watching MMA (I have a huge collection of videos and watch every UFC PPV), listening to podcasts, American history, exercise, and hardcore pornography.

Repairing computers and playing guitar are an old hobbies I don't do much of any more.

I'm gonna get into guns before the liberals take them away.

Im a big comic collector (have worked in a comic shop in the past for 4 years...my bro owns the very shop I worked now but he bought it after I worked there. Occasionally he gets me to fill in there when he's under staffed and I'm not busy with my actual job)...
I'm big on music, movies and (sometimes even) reading books without pictures in as well. I had aspirations to be a writer or artist before I became old and jaded...I was a dj in a club that played 90s style 'grunge' type music for about 3 years when I was still young and cool (lie, I was never cool, not even sure I was ever young)...and sometimes friends get me to dj at their weddings/parties but that's very part time...

I Know how you feel. LOL With the economy being the shit that it is, nows the best time to make a name for yourself.

You into aquaristics too? Cool!

I have 6 aquariums. I love tropical fish.

I also love gardening. Both flowers and vegetables now that I finally have my own little garden.

Ah, totally forgot! I also love playing Magic the Gathering. Recently been getting into the Commander format, but still have a ton of 60-card decks to mess around with, too. Never done anything outside casual play though.

I want doing girls to be my hobby, but it is like it's never going to happen.

Walking.

Marching for big distances. Like this (though this picture shows the extreme): 

In fact, tomorrow I'll go for another 50 kilometer walk. Once every year there's the biggest marching event in the world here in Holland. 45,000 people participate, 1.5m spectators and visitors and a total of 200 kilometers walk. It's in a little over 2 weeks from now, can't wait !

Besides that, I collect numerous useless things, but the most prominent stuff I collect, besides video games, are coins. Not really a real hobby though, I don't spend any time on it.

Also, I'm nearly an architect, so naturally I'm interested in buildings too. I like visiting cities to see the sites. Also, my favorite day off would be spent in an amusement park, riding rollercoasters and such. Though I'm not sure those two can be qualified as 'hobbies'.

I've sort of been a one-trick pony with regard to gaming most of my life. However, I'm trying to reawaken my childhood love of creative writing and I have had a lengthy film script on the go since last year. I'm also looking into singing, guitar, and acting lessons.

Gotta round out that character somehow, right? :)
