All great achievers, all successful people , are those who have been able to control their time. All human being have been created equal in one respect: each person has twenty-four hours each day.
We must give must give our best time to our most challenging situation. It's not how much we do that matters ; its how much we get done. I remember what my dad always telling me "Don't spend a dollar's worth of time for ten cent's worth of results. We should choose to watch our time not our watch.
