I was really upset when one of my students fell asleep during my afternoon class yesterday. When she was asked... she said that she didn't have enough sleep. It turned out that she slept late at night and woke early in the morning.
I don't really understand students these days because they don't really have their own time management. Yes I know... a student's life can be a hectic one with many things to do in a day, but still, without proper time management, you might lose control of yourself.
As a student, you should know how to prioritize things and how to control your own schedule. It is all about your physical and mental state - if you lose control, you might have to face difficulties in life... and somehow, those difficulties will lead to your FAILURE!!!
So... have your own time management.. don't simply do things without planning anything. Remember... if you fail to plan your life, you are planning to fail in your own life....
