All improvement in your life begins with an improvement in your mental pictures.

Your ability to get along well with others will determine your happiness and success as much as any other factor.

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.

Attitude and personality are as important as experience and ability.

Perhaps the very best question that you can memorize and repeat, over and over, is, 'what is the most valuable use of my time right now?'

Your success in your career will be in direct proportion to what you do after you've done what you are expected to do.

Your ability to work with others on a complex task is a critical skill for advancement at work.
