All competent authorities agree that personality plays a large part in determining the degree of success that may be achieved in all walks of life. The search for happiness is our most common quest. Everyone needs some "happy isles" if he is to weather the storms of life. If everyone could develop desirable personality traits, learn to get along with other people, make and keep friends, adjust well to life's situations--then we should be able to attain real happiness. Some people attain deep and lasting happiness; others attain scarcely any. One's happiness depends upon the person himself.
