When you were born, you were crying and everyone around you was smiling. Live your life so that when you die, you're the one who is smiling and everyone around you is crying. You never know when these people might appear, but when you lock eyes with them, you know that every moment you spend with them, they will affect your life in some profound way. And sometimes things happen to you that may seem horrible, painful and unfair, but on reflection you realize that without overcoming these obstacles you would have never realized your potential, your strength, your willpower, your heart. Everything happens for a reason.
Nothing happens by chance or by means of good luck.
Ilness, injury, love, lost moments of true greatness and sheer stupidity all occur to test the limits of your soul. The people you meet affect your life. The successes and downfalls that you experience help create who you are, and the bad experiences can be learned from. In fact, they are probably the most poignant and important ones. If someone hurts you, betrays you or breaks your heart, forgive them because they have helped you learn about trust and the importance of being cautious to whom you open your heart to.
