Everyone is busy these days, too much of things to do in a limited time. Especially for students they need to go to classes, play games, work out in gym, extra coaching classes, outing with friends etc. but they do manage the schedule very nicely. By fixing time for each and every thing, they do things at the right time they have planned its called time management. But when we grow up, we tend to get lazy or relax our self when something is waiting to be done. That will create frustration in you, when the things are not done. You may also try to do things in haste. So do have proper time management to be a winner in life.
