Happiness is simply a state of mind in which our thinking is pleasant a good share of the time.

Loneliness is caused by an alienation from life. It is a loneliness from your real self.

The most delightful surprise in life is to suddenly recognise your own worth.

Another cause of confusion, and the resulting feelings of nervousness, hurry, and anxiety, is the absurd habit of trying to do many things at one time.

You make mistakes. Mistakes don't make you.

What is opportunity, and when does it knock? It never knocks. You can wait a whole lifetime, listening, hoping, and you will hear no knocking. None at all. You are opportunity, and you must knock on the door leading to your destiny. You prepare yourself to recognize opportunity, to pursue and seize opportunity as you develop the strength of your personality, and build a self-image with which you are able to live - with your self-respect alive and growing.

Your nervous system cannot tell the difference between an imagined experience and a ‘real’ experience.
