Wal-Mart's size and scale is so vast they literally have the ability to change the face of the entire country. If Wal-Mart were to make a decision tomorrow to refuse to sell a single product made with partially hydrogenated oils, for example, we'd probably see rates from heart disease decline a few years later. That's how powerful Wal-Mart is.

Great leaders state out loud what they intend to do and in doing so, they get things done.

Authenticity is about imperfection. And authenticity is a very human quality. To be authentic is to be at peace with your imperfections. The great leaders are not the strongest, they are the ones who are honest about their weaknesses. The great leaders are not the smartest; they are the ones who admit how much they don't know. The great leaders can't do everything; they are the ones who look to others to help them. Great leaders don't see themselves as great; they see themselves as human.

Leaders, whatever the size of their organizations, are those willing to put the interests of other people before their own.
