Throughout my career, I have discovered and rediscovered a simple truth.It is this: the ability to concentrate single-mindedly on your most important task, to do it well and to finish it completely, is the key to great success, achievement, respect, status and happiness in life.

Everything you do to improve your physical well-being will have a positive impact on how good you feel about yourself.

Change your thinking, and you will change your life.

What you concentrate on largely determines the quality and quantity of the results that you get and the success that you enjoy.

Simplify the task. Continually look for faster, better, easier ways to get the job done.

A goal that is not in writing is like cigarette smoke: It drifts away and disappears. It is vague and insubstantial. It has no force, effect, or power. But a written goal becomes something that you can see, touch, read, and modify if necessary.

Offer your customers a long-term relationship, then do everything possible to build and maintain it.
