The amount you laugh in your relationships with others is the true measure of the health of your personality.

There is an interesting point about the price of success: It must always be paid in full-and in advance. Everyone wants to be successful. Everyone wants to be healthy, happy, thin, and rich. But most people are not willing to pay the price.

Develop a mentor at each stage of your career - someone who will give you guidance and advice.

Think about your goals at every opportunity throughout the day.

The predominant quality of successful people is optimism.... Your level of optimism is the very best predictor of how happy, healthy, wealthy, and long-lived you will be.

Our mind is the most valuable possession that we have. The quality of our lives is, and will be, a reflection of how well we develop, train, and utilize this precious gift.

Throw yourself wholeheartedly into your work; the more you enjoy it, the better you get.
