If you want to be a great leader, remember to treat all people with respect at all times. For one, because you never know when you'll need their help. And two, because it's a sign you respect people, which all great leaders do.

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.
