What's difficult in life is to stay centered when somebody does or says something that tempts us to close our hearts because their heart was closed. That is hard. But that is also how we grow. We go through those circumstances in order to evolve into people who can hold to our loving center no matter what the world throws us.
When love beckons to you, follow him, Though his ways are hard and steep. And when his wings enfold you yield to him, Though the sword hidden among his pinions may wound you. And when he speaks to you believe in him, Though his voice may shatter your dreams as the north wind lays waste the garden.
Kahlil Gibran (1883 - 1931)

We pay a heavy price for our fear of failure. It is a powerful obstacle to growth. It assures the progressive narrowing of the personality and prevents exploration and experimentation. There is no learning without some difficulty and fumbling. If you want to keep on learning, you must keep on risking failure - all your life.
