You've got to be able to manage change. You've got to be able to learn new tasks.

I think companies have a big problem making a big transition, so leaders get replaced.

The truth is we have a consistent purpose that we got from our founder, some values that we share - those are persistent, too. It's not just change. But that's the thing that people underestimate about Walmart right now, that it has an ability to change.

As we make investments in technology and learn how to automate things, we want our people to learn that and go with us.

One of the things that can keep you from going away is an openness to change. That's the point.
