Everybody has 24 hours a day. But most people say that they don't have enough time to do this or that. As long as we know how to manage our time by scheduling our activities, this kind of saying "Not enough time" will be lesser.
People who don't know how to manage time wisely will find many problems in their lives, such as: unfinished jobs, abnormal rest and work, sometimes they even have to burn the midnight oil to finish the work they could do during the day. It's not easy to manage time, though. Hence, many of them keep on finding excuses for not doing something.
Happiness really comes to those who have learned time management and carefully scheduled their activities. Those who can manage time wisely are actually people who have cultivate the habit of using time since their childhood or at least they are those who have ever wasted their time and then realized about it.
