Head to the waterfront district and find Armand Christophe at midnight (the guy for the thieves guild quests). Steal the key to the imperial trading company from him (don't worry about failing -- he will say he doesn't need it anyway if you fail), then go to the place and go upstairs. Damian Magius will be sleeping. He will not wake up no matter how fast you walk. Now, take a rubber band and put one end over the joystick, then put the other end under and around to the grip on the other side and leave it going for however long you want. You'll earn experience and eventually read level 100.
