Everything happens for a reason. Nothing happens by chance or by means of good or bad 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, if they be events, illnesses or relationships, life would be like a smoothly paved, straight, flat road to nowhere.
Hold your head up because you have every right to. Tell yourself you are a great individual and believe in yourself, for if you don't believe in yourself, no one else will believe in you either.
