As free human beings we can use our unique intelligence to try to understand ourselves and our world. But if we are prevented from using our creative potential, we are deprived of one of the basic characteristics of a human being.
What I must do is all that concerns me, not what the people think. This rule, equally arduous in actual and in intellectual life, may serve for the whole distinction between greatness and meanness.
Remember this: When you cross my doorstep, you have already been raised. With what you have learned...you know the difference between right and wrong. Do right. Don't anybody raise you from the way you have been raised. Know you will have to make adaptations, in love, in relationships, in friends, in society, in work, but don't let anybody change your mind.
