You are a game changer
Sometimes people come into your life and you know right away that they were meant to be there, to serve some sort of purpose, teach you a lesson, or to help you figure out who you are or who you want to become. You never know who these people may be (possibly your roommate, neighbor, coworker, long-lost friend, lover, or even a complete stranger) but when you meet them, you know at that very moment that they will affect your life in a magical way.
And sometimes things happen to you that may seem horrible, painful, and unfair at first, but in reflection, you find that without overcoming those obstacles you would have never realized your potential, strength, willpower, or heart. Everything happens for a reason, nothing happens by chance or by means of luck. Illness, injury, love, lost moments of true greatness, and sheer stupidity all occur to test the limits of your soul. Without these small tests, whatever they may be, life would be like a smoothly paved, straight, flat road to nowhere. It would be safe and comfortable, but dull and utterly pointless.
The people you meet who affect your life, and the success and downfalls you experience help to mould you. Even bad experiences can be learned from. Make every day count! Appreciate every moment and take from those moments everything that you possibly can for you may never be able to experience it again. Believe in yourself, create your own life then go out and live it with absolutely no regrets.
