Read a series of books, buy an Xbox, go fishing, hunting, scuba diving, sky diving, paintball, restore a car, take walks in the park, do drugs, go to the gym, pull a prank, start a business, street racing, get a job, get more good friends, heist a bank, play tennis, read the dictionary, adopt a child, watch paint dry, tame a wild animal, join the military, take a nap, or build a house. This list could continue for hours use your imagination.
Try to get involved in daily activity. If you're in school, that can be boring enough. You can try though, to find after-school activities. As for weekends, join a group or make plans with friends. The older you get, the faster years go by. Believe me :)
