"Do something instead looking in facebook like doing homework,study for midterm or test, excercise, hang out with friend, relax with music or radio even Ipod, read book and ready to next lesson for study. Yeah, that facebook is wasting time. Check your body feel now like borning or nothing to do. Tried to something and don't look facebook but only birthday or even friend add on, okay. Tried it and get good grade for G.P.A in college."
