One of the most valuable principles a person may ever learn in their lifetime is that every person that is in their life, is in their life for a reason. Some people are in your life to be your genuine friend, and to just help you become the best you that they may possibly help you to become. Some people are in your life to test you, to show you that things may not always be what you think they may seem.
Some people are in your life to teach you. Sometimes we are full of gifts and talents that we have no clue that are inside of us, and some are put in our lives to help us to see these gifts out of our hearts and to develop them.
Some people are in your life solely for themselves. But it is these people who will also teach you many lessons, one must be careful to let a fool bring him/her to their own level. Different people will teach us all different things, but in every lesson one must always remember that life is too short to hold on to anger and spite. Take the lessons you learn in your past, and use them to help the person you have become in the present day..
