I am a TV sports reporter, so I am one of those lucky people who actually get to work with something that might be called a hobby. I'm into sports, and I've loved the game of football (soccer) for many years, so what can be better than presenting your own interests to the masses? This weekend, I'll be doing live commentary for the first time, which will surely be interesting. If I do well, I might well be in for a lot of more work in that field in the years to come, on national TV. Which would be nice.
Apart from that, I'm very interested in music. As I've said elsewhere on this website, I sing, and I listen to a lot of music - a lot of different music, actually. I'm also very fond of movies - my DVD collection is growing at a quicker rate than it should (currently around 500 DVDs, some classic, but most of them from the late 80's and newer). My CD collection is no longer growing as rapidly (currently around 750 CDs), as I'm satisfied with what I've got and will only expand it if I really like the music.
And then I read - the common popular fiction stuff, I guess.
