If I reveal myself without worrying about how others will respond, then some will care, though others may not. But who can love me, if no one knows me? I must risk it, or live alone.

Crises marked by anxiety, doubt, and despair have always been those periods of personal unrest that occur at the times when a man is sufficiently unsettled to have an opportunity for personal growth. We must always see our own feelings of uneasiness as being our chance for making the growth choice rather than the fear choice.

So it is that God tugs at a pilgrim's sleeve telling him to remember that he is only human. He must be his own man, remain in exile, and belong to himself. He must pay attention to his own feelings and to the meaning of what he does, if he is to be for himself, and yet for others as well.

~ Sheldon B. Kopp

So it is that there is nothing to be taught, but yet there is something to be learned.
