We are built to conquer environment, solve problems, achieve goals, and we find no real satisfaction or happiness in life without obstacles to conquer and goals to achieve.

Happiness is the art of relaxation.

Change your mental imagery, and the feelings will take care of themselves.

Live in the present. The past is gone; the future is unknown - but the present is real, and your opportunities are now.

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

Your most important sale in life is to sell yourself to yourself.

Times will change for the better when you change.

Low self-esteem is like driving through life with your hand-break on.

This is where you will win the battle - in the playhouse of your mind.

Every day you must try to make your own self-image grow; this you can do.

Adopt the motto: It doesn't matter who's right, but what's right.

You will act like the sort of person you conceive yourself to be.

A human being always acts and feels and performs in accordance with what he imagines to be true about himself and his environment.

Self-improvement is the name of the game, and your primary objective is to strengthen yourself, not to destroy an opponent.

If you make friends with yourself you will never be alone.

We, whoever we are, must have a daily goal in our lives, no matter how small or great, to make that day mean something.

Our self image, strongly held, essentially determines what we become.

Self-esteem is as necessary to the spirit as food is to the body.

To change a habit, make a conscious decision, then act out the new behavior.
