Real wisdom can't be transmitted by words. Reading books by dead men only teaches you what they said. You must live and learn. You cannot learn it then live it. At best, you'll only achieve mimicry.
I know it is religious and not strictly philosophical, but still: Serenity prayer God, give me grace to accept with serenity the things that cannot be changed, Courage to change the things which should be changed, and the Wisdom to distinguish the one from the other.
