One day my teacher said, “ Life is a game of chess, and the other player is time.” From that moment, I knew I had to enjoy my life. Do not waste time, because, you know, time will not come back. You cannot buy it. It is one of those things in life that you must really, really value.

When you see an opportunity, take it. You might not get it back. Never let an opportunity pass. And if it is too hard, remember that in the middle of every difficulty lies an opportunity.

Remember, you cannot choose how you' re going to die, or when. You can only decide how you' re going to live. Study as if you were going to live forever; live as if you were going to die tomorrow. Don' t just think of the present, but also think of your future. Your future is yet another chapter in your life and another way to live it.

Every single living thing has a purpose in life. "The purpose of life is a life of purpose," said Robert Byme.   

Learn to use time wisely, take opportunities, and enjoy life. We can discover the meaning of life in three different ways: (1) by doing a deed;  (2) by experiencing a value;  (3) by suffering life. So, what are you buying with yours?
