Don't stifle your career by limiting you knowledge.

"To coach" comes from the root meaning "to bring a person from where they are to where they want to be."

Give away everything you have learned. If for no other reason, do it selfishly; in order to get more, you must give more.

Leadership can't be claimed like luggage at the airport. Leadership can't be inherited, even though you may inherit a leadership position. And leadership can't be given as a gift - even if you've been blessed with an abundance of leadership skills to share with someone else. Leadership must be earned by mastering a defined set of skills and by working with others to achieve common goals.

Your job is not to lower the bottom by adjusting for and accommodating the lowest-performing employees. You should be raising the top by recognizing and rewarding superstar behavior.

You will never have enough time to do everything you need to do, so what you need is a crystal clear understanding of the important things you have to do.

Guard your integrity as if it's your most precious leadership possession, because that is what it is.
