Volunteer for something extra, volunteer for something hard. One of the reasons that I got the opportunities that I got was that I would raise my hand when my boss was out of town and he or she was visiting stores or something, and someone needed to pinch hit and go to a meeting, I would go, and if I knew the answer to the question that came up, I'd share it, if I didn't, I'd say, "I don't know, but I'll find out fast and get back to you." I then put myself in an environment where I became a low risk promotion because people had already seen me do the job.

There just aren't that many opportunities in the world that are that big, and for a company like Walmart that needs to move the needle in a big way, you have to take some big bets, but if you're going to take that much risk, the reward has to match up.

We need to learn how to become a digital enterprise, but we understand that we're a company made up of 2.2 million associates, and that human interaction in the future will matter.

The most important single thing is to focus obsessively on the customer. Our goal is to be earth's most customer-centric company.

All businesses need to be young forever. If your customer base ages with you, you're Woolworths.

Many are stubborn in pursuit of the path they have chosen, few in pursuit of the goal.
