Put first things first , prioritize and manage your time (:
"Putting first things first means doing to the most important thing in life. It means being clear about your priorities and acting on them."
How do you become master of your own time?
Many people unconsciously fall in the trap of getting caught up in non-important things. They neglect the larger life priorities until it becomes too late to act on them. To become a master of your time, you need to first be aware of your priorities in the larger context of your life.
