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.

The more you work, study and develop your ability to contribute more to the lives and well-being of others, the better life you will have in all areas.

The biggest enemies we have to overcome on the road to success are not a lack of ability and a lack of opportunity but fears of failure and rejection and the doubts that they trigger.

Telling is not selling. Only asking questions is selling.

Self-confidence comes naturally when your inner life and your outer life are in harmony.

No one lives long enough to learn everything they need to learn starting from scratch. To be successful, we absolutely, positively have to find people who have already paid the price to learn the things that we need to learn to achieve our goals.

Incorrect assumptions lie at the root of every failure. Have the courage to test your assumptions.
