I divide all readers into two classes: those who read to remember and those who read to forget.

Those who decide to use leisure as a means of mental development, who love good music, good books, good pictures, good plays, good company, good conversation - what are they? They are the happiest people in the world.

The principle of happiness should be like the principle of virtue: it should not be dependent of things, but be a part of personality [and character].

The kind of happiness that stays with you is the happiness that springs from inward thoughts and emotions.

Why is it that so many people are afraid to admit they are happy?
