Really great people make you feel that you, too, can become great.

What I must do is all that concerns me. This rule, equally arduous in actual and intellectual life, may serve for the whole distinction between greatness and meanness. It is harder because you will always find those who think they know what is your duty better than you know it.

Let your heart be awakened to the transforming power of gratefulness.

Men are only as great as they are kind.

Great spirits have always encountered violent opposition from mediocre minds.
