Pain isn't a lot of fun, at least not for most folks, but it is utterly unique to life. Pain--physical, emotional, and otherwise--is the shadow cast by everything you want out of life, the alternative to the result you were hoping for, and the inevitable creator of strength. From the pain of our failures we learn to be better, stronger, greater than what we were before. Pain is there to tell us when we've done something badly--it's a teacher, a guide, one that is always there to both warn us of our limitations and challenge us to overcome them.
