Essentially, mistakes are made in order to allow people to learn from them. Therefore, if one knows that he or she has had issues in the past with time management, they can look at how they acted in the past and change those behaviors in the future.
For example, if a person has historically always run late, one solution to curbing the behavior is to allot more time in order to get to the destination on time. Instead of allowing for thirty minutes to get somewhere, then they should allot for forty-five. If this still makes them late, they should allot for an hour the next time.
Other ways to manage time is not to put things off. For example, if a person has a project due and they have put the project off in the past until the last moment, his or her time management is not well managed. Instead of looking at the deadline as the time to begin, one could look at the deadline as a time to have the third edit completed.
Essentially, time management is something everyone must do. If a person has had problems in the past, he or she must examine why the problem exists based upon the history of the problem. Changing the problem is as easy as getting up earlier, starting on projects sooner, and allowing for bumps along the way.
