I believe that there is something far nobler than loyalty to any particular man. Loyalty to the truth as we perceive it - loyalty to our duty as we know it - loyalty to the ideals of our brain and heart - is, to my mind, far greater and far nobler than loyalty to the life of any particular man or God. . . .

Do not tell me that you have got to be rich! We have a false standard of greatness in the United States. We think here that a man must be great, that he must be notorious; that he must be extremely wealthy, or that his name must be upon the putrid lips of rumor. It is all a mistake. It is not necessary to be rich or to be great, or to be powerful, to be happy. The happy man is the successful man. Happiness is the legal tender of the soul.Joy is wealth.

When one of your children tells a lie, be honest with him; tell him that you have told hundreds of them yourself. Tell him it is not the best way; that you have tried it. Tell him as the man did in Maine when his boy left home: "John, honesty is the best policy; I have tried both."
