I never actually get bored.
First thing I do everyday online is check CyberNations, Hotmail, Myspace CF and sometimes Youtube, then I just play WoW for several hours lately... haha, Either that, or guitar and vocal practise in my room.
I don't play sport anymore and I don't really watch TV but I'm trying to watch every season of The X-Files because by dad's bought most of the DVD collection so I'm about 3 seasons in out of 9, then I gotta see the 1998 movie because the second film is released in America by July 25th so I'm not sure how long it'll be until I can see it.
I'm a fairly anti-social person because I have alot to do at home but I occasionally see some of my friends from my old social circle before I left school.
Find a creative hobby, find a series in books or movies that interest you and get some decent multiplayer games.
