Develop an 'attitude of gratitude.' Say thank you to everyone you meet for everything they do for you

You can develop any habit or thought or behavior that you consider desirable or necessary.

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

A hundred years ago-even 20 or 30 years ago-it was possible, if not always easy, to close major business by calling on and satisfying a key decision-maker. Today, every piece of business entails multiple decisions, and those decisions are virtually never made by the same person. Not only do you have to contend with multiple decisions, but the people who make those decisions may not even work in the same place.

Ideas will be the major source of new wealth.

Courage comes from acting courageously on a day-to-day basis.

You cannot control all of what happens to you, but you can control your attitude toward all of what happens to you...You can choose to be happy and grateful rather than disappointed and bitter, by focusing on how it could have turned out worse but didn't, rather than how it could have turned out better but didn't.
