It means make time for the things that are really important. This entails prioritizing and planning. Many people are opposed to planning, because they say it destroys their sense of spontaneity. If spontaneity is taking you where you really want to go with your life, then you do not need to worry about time management. For the majority of us, spontaneity means waiting for a break in the tedium.
Planning eliminates the tedium, and provides movement into a productive life.
It does not mean you will not be able to do the things you want to do. It means now you will plan for leisure, work, school, studying, relaxation, relationship building, and any other worthwhile pursuit. One necessary tool in your journey toward time management is a planner. This can be as complicated as the exclusive Franklin Planner, or as simple as a pocket size weekly calendar. There should be space for each day of the month, and it is important that you carry it with you so that it can be used.
