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.

More often than not when we do not like our work, it's not necessarily because of the work itself. But more often because of the people we work with and more importantly because of the lack of leadership. It is amazing how inspired and motivated we can be when we like the people and when we feel like we show up to work because our leaders care about our wellbeing. It is kind of incredible actually.

Great leaders must have two things: a vision of the world that does not yet exist and the ability to communicate that vision clearly.

The irony is that the best thing we can do is, well one option, is to quit job we don't like. You don't always have to quit, and quite frankly, option two is to try to help others solve the problem that you are struggling with.

Give someone responsibility and they will do their best. Make them accountable and they will do even better.

There are leaders, and there are those who lead. Leaders are those who hold a position of power or authority. But those who lead are those who inspire us. And it's those who start with why, that have the ability to inspire those around them or find others who inspire them.
