Don't you have much more faith in ideas that you discover for yourself than in ideas that are handed to you on a silver platter?

You must have a good time meeting people if you expect them to have a good time meeting you.

Act as if you were already happy and that will tend to make you happy.

Criticism is futile because it puts a person on the defensive and usually makes them strive to justify themselves. Criticism is dangerous, because it wounds a person's precious pride, hurts their sense of importance, and arouses resentment.

If you want to be happy, set yourself a goal that commands your thoughts, liberates your energy and inspires your hopes. Happiness is within you. It comes from doing some certain thing into which you can put all your thought and energy. If you want to be happy, get enthusiastic about something.

Today is our most precious possession. It is our only sure possession.

It never hurts a fool to appear before an audience, for his capacity is not a capacity for feeling.
