It's not really related, but since you loved quotes, I'll add in three of my favorites:

"That which does not kill us makes us stronger." -Friedrich Nietzsche (which every Conan fan remembers)

"We are not here to curse the darkness; we are here to light a candle. As Winston Churchill said on taking office some twenty years ago: If we open a quarrel between the present and the past, we shall be in danger of losing the future. Today our concern must be with that future. For the world is changing. The old era is ending. The old ways will not do." -JFK

"Our greatest glory is not in never falling, but in getting up every time we do." -Confucius
