3 - 4 hours a day? You have no life. Considering you sleep at least 8 hours a day, go to school another 8, spend another hour eating, about another hour waiting/getting ready for school/ etc.. each day, that leaves 5.9 hours left for you to "have a life with" (There's only about 23.99 hours in a day) Because you have nothing to do after school, I'd suggest getting a job, or at least making yourself good at something useful. When you add everything up, right now you're spending most of your "life" on your computer. Join some sports or something, or at least do something constructive on your computer. By the way "only four hours a day" equals 116,800 hours in your life. Assuming you live about 70 or 80 more years, that's 26.67 years of your "conscious" life spent at your computer.
