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.

I think as we all work to learn and navigate the future towards a world where AI fulfills its promise, the best way to do that is to work together and to share information and learn together. It'll speed up our ability to get ahead of this so that we can do a better job of setting our associates up for success.

It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

We grew this business with the store operators and the merchants making all the decisions, I got to be one of the merchants and it was a lot of fun. But to put the customer in charge, you have to start with design.

One way to think about Walmart is a very large river of merchandise, moving from raw material to a customer and anytime that river of merchandise has imperfections, we either have an out of stock or we have some sort of overstock that creates additional costs, labor markdowns, accidents, damages.

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.
