I can be changed by what happens to me. But I refuse to be reduced by it.

You cannot have what you do not want.

I never resist temptation because I have found that things that are bad for me do not tempt me.

Three things cannot be long hidden:

Men of perverse opinion do not know the excellence of what is in their hands, till some one dash it from them

One is happy once one knows the necessary ingredients of happiness: simple tastes, courage, and love of work.
