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.

Today, we still have more than 300,000 U.S. associates who were with us since 2015 and are now leading teams, running stores and clubs, and continuing to grow their careers. Their stories are a reminder that when people are given opportunity, they make the most of it - and a culture of opportunity creates a cycle where happy associates lead to happy customers and members, and vice versa.

2/3 of our management associates come from our hourly ranks. We put in place academies to help people with education. We've put a dollar a day college program in to help people get college hours if they want to advance their degrees.

Ten years ago, we committed to investing in our associates through higher wages, new training opportunities, and changes to our scheduling and education programs. It was a step grounded in the belief that putting people first is always the right thing to do. These investments sparked momentum in our stores that we still see and feel today.

I think most Americans probably don't know what a tech makes that helps take care of our stores and clubs and that we can help them learn how to be a tech. The same thing's true for our drivers. So we have a need to get the word out so that people know there are some great jobs.

There are all these things that add up into this business that's Walmart that keeps it really interesting. At the root of it all, though, it's a people business and it's a merchandising business. Today, it's increasingly a technology business. The supply chain is critical, of course, and real estate still plays a key role.
