The 'self-image' is the key to human personality and human behavior. Change the self image and you change the personality and the behavior.
A human being always acts and feels and performs in accordance with what he imagines to be true about himself and his environment.
It is no exaggeration to say that every human being is hypnotized to some extent either by ideas he has uncritically accepted from others or ideas he has repeated to himself or convinced himself are true. These negative ideas have exactly the same effect upon our behavior as the negative ideas implanted into the mind of a hypnotized subject by a professional hypnotist.
Happiness is native to the human mind and its physical machine. We think better, perform better, feel better, and are healthier when we are happy.
Science has now confirmed what philosophers, mystics, and other intuitive people have long declared: every human being has been literally "engineered for success" by his Creator. Every human being has access to a power greater than himself.
The biggest secret of self-esteem is this: Begin to appreciate other people more; show respect for any human being merely because he is a child of God and therefore a thing of value.
