Rage against the world, if you like, but quietly, or the Guardians will awake.
Boast quietly, with decorum.
Imprudence relies on luck, prudence on method. That gives prudence less edge than it expects.
Curiosity makes loneliness.
If your nose is up in the air, you cannot see where you are going.
I criticize myself ruthlessly, but never mention the faults of which I am truly ashamed.
