details:
If we use our childhood to play, teenage to cherish; then we use our mid-life to work hard ,and enjoy our later life.
Gradually, I would grow up ,and be a little older, mid-aged,and old. We can't predict the future, but we can make it by our hands.It's too early for us to say what future can be. and whatever we say now, it's not campared with what we will do in the future.
Time is on its own , it wouldn't care about you.And world wouldn't change for you. The thing you can change is yourself.Forget about the past. It's not too late for you to work hard now.
