Always tell the truth. That way, you don't have to remember what you said.

To get something you never had, you have to do something you never did.

Everything is hard before it is easy.

No human race is superior; no religious faith is inferior.

My courage always rises at every attempt to intimidate me.

A man who dares to waste one hour of time has not discovered the value of life.

A gem cannot be polished without friction, nor a man perfected without trials.
