A doubtful friend is worse than a certain enemy. Let a man be one thing or the other, and we then know how to meet him.
We learn from the things we suffer.
He that is hard to please, may get nothing in the end.
Always stop to think whether your fun may be the cause of another's unhappiness
It pays to be content with your lot.
Bad as any government may be, it is seldom worse than anarchy.
