I don't. School, writing, the occasional doodle or photoshop, tv, eating, exercise, and world domination already leave me with no more than three hours to sleep XD
When I'm bored, I watch the latest episode of Doctor Who on BBC iplayer. It's a pretty good remedy, actually.
^^you're bored..?? and I thought you were too busy rulin' the world......... oh, I forgot, you ain't emperor of the world are you...??lol
When I'm bored and have nothing else to do (which isn't usually the case - I always have stuff to do, I'm just a chronic procrastinator) - I like to go to Deviant Art and look at pictures that I could use as desktops to make me happy from time to time. I LOVE Children's Illustrators. Sometimes I go online and make a wishlist of stuff I eventually wish to buy or want bought for me. =P Dresses, sheet music, hats, earrings..
