I learned that courage was not the absence of fear, but the triumph over it. I felt fear myself more times than I can remember, but I hid it behind a mask of boldness. The brave man is not he who does not feel afraid, but he who conquers that fear.
I am fundamentally an optimist. Whether that comes from nature or nurture, I cannot say. Part of being optimistic is keeping one's head pointed toward the sun, one's feet moving forward. There were many dark moments when my faith in humanity was sorely tested, but I would not and could not give myself up to despair. That way lays defeat and death.
