Proverbs 13:12
Hope deferred maketh the heart sick: but when the desire cometh, it is a tree of life.

Understanding the cycle of life gives us a better grasp of how we conduct our lives. Sometimes we need to experience failure so that we might learn how to stand from the struggle of life. There are lessons of life that you will only learn in experiencing it. When you don't understand how the school of life works, you will live in despondency. You will not hope for the better but wish for extinction.
