Sometimes, people come into your life and you realize that they are there for some purpose, to teach you a lesson, or to help you to know who you are or who you want to become. You'd never know who these people may be, your friend, your classmate, you neighbor, your co-worker, your teacher, or even a stranger, but they will deeply affect your life in some way. And sometimes things happen to you that may seem unfair, painful and horrible as first, but later, you realize that without overcoming those difficulties you would never know your strength, willpower or potential. Everything happens for a reason. Nothing happens by chance or by means of good luck. Illness, great achievement, love, injury and failure all come to test the limits of your soul.
