Life is a precious gift which is given to us for only once. But the life is directly effected by the time. As the time goes on, the life is directly effected. It can be said that we are the slave of the time. We have to follow each and every rules and regulation of time. So many people of the world manage their time to achieve their goals. They mange their time by making time table which helps them to do the work in specific time.
