I am late regularly
Perhaps, you just do not have time feeling. Anyway, it is possible to train it. Start with the simple alarm clock in order to work out your reflexes. When it is high time to go out, alarm yourself. Repeat it for a week, or two weeks in order to do that without reminding.
Or you can not manage your time effectively. In this case, you have to take a sheet of paper and write down what you use your time for. Point out every moment, every event, regular or not. Try to understand what actions take much time, but you could reduce them without harm to your usual lifestyle. Perhaps, it is worthy to go to bed a little bit earlier in order to wake up next morning easier. If you are to be at the place where you have never been before, take some time in advance. Do not believe that you are going to use the racket to reach the place.
To deep into the human mind, it is possible to discover other reasons of being late. They say about the roots in the childhood. As a matter of fact, the parents could compare you with your sister who was the best student, used to draw, run or jump better than you did. She succeeded to do the things in time and beat any record. Logically, a person tries to suppress inner feeling of dissatisfaction which turns to be "I am late regularly" behavior line.
Whatever the reason is, you have to work on it carefully. You could be great in time management, if you leave the excuses and start indicating every minute of yours if you waste it or not.
