To preserve an unclouded capacity for the enjoyment of life is an unusual moral and psychological achievement. Contrary to popular belief, it is not the prerogative of mindlessness, but the exact opposite: It is the reward of self-esteem.

Your life is important. Fight for it. Honour your highest potentials.

You have a right to your feelings. Your feelings are there to tell you something, but they are not infallible guides to behavior.

Our motive is not to prove our self-worth, but to live up to our possibilities.

A productive purpose to which you give yourself fully and joyfully is one of the great adventures of life. It is a uniquely human source of happiness.

The world belongs to those who persevere.

One of the hardest expressions of self-assertiveness is challenging your limiting beliefs.
