Never trust the advice of a man in difficulties.
It is one thing to say that something should be done, but quite a different matter to do it.
Don't let your special character and values, the secret that you know and no one else does, the truth - don't let that get swallowed up by the great chewing complacency.
The hero is brave in deeds as well as words.
Destroy the seed of evil, or it will grow up to your ruin.
I am sure the grapes are sour.
