“Take chances, make mistakes. That's how you grow. Pain nourishes your courage. You have to fail in order to practice being brave.”
“Mistakes are the usual bridge between inexperience and wisdom.”
“To make no mistakes is not in the power of man; but from their errors and mistakes the wise and good learn wisdom for the future.”
“No, that is the great fallacy: the wisdom of old men. They do not grow wise. They grow careful.”
“Our purpose in life is to grow in wisdom and in love.”
