What does not kill me, makes me stronger. The weak can never forgive. Forgiveness is the attribute of the strong. It is unwise to be too sure of one's own wisdom. It is healthy to be reminded that the strongest might weaken and the wisest might err. The strongest is never strong enough to be always the master, unless he transforms strength into right, and obedience into duty. That's one small step for a man, one giant leap for mankind.
