You can't change people but you can effect a change in them by your behavior.
When you focus on how people feel about what they are saying, you increase the level of true concern you have for others. You actually start to become the person you thought you were pretending to be: a true leader!
Position yourself to succeed first by building good relationships with the right people; and then put your effort and expertise behind that!
