In some circles, Walmart has this reputation of being really tough. I would say we're tough on behalf of the customer, but we always try to be fair, and if you look at the financial results of our suppliers, they've done really well, and P&G still makes more money than Walmart does after all this time, so this has worked out well for everybody, but we do keep on the pressure on behalf of the customer.

I really love retail history. We started our first Supercenter in 1988, prior to that we were operating general merchandise discount stores, and we tried some big hypermarkets copied from Europe and they had failed miserably, but we tried to downsize it and make it a Supercenter and it started working.

We get to do business all over the world, and it's rare to have such a big economy [India], growing so fast, and creating so much opportunity for so many. We want to be part of the process to strengthen the country, to serve its citizens and to demonstrate that we're a trusted partner across all these dimensions.

I think real estate is really core, but you just nailed why I'm still here and loved retail - it's because of the breadth of it. I didn't appreciate how interesting retail was until I got started. You have to have a customer relationship, but you need leadership skills, servant leadership characteristics.

Retail is detail, and that plays out throughout the international business as well. Today's portfolio has got omnichannel businesses in Mexico, Central America, Canada, China, but we also have an e-commerce marketplace in India with Flipkart and our financial services business in India, PhonePe - those are a bit different, but the other markets have a lot of commonality strategically.

If you fast-forward through the years, there was a period of time when there was too much debate inside the company about the significance of e-commerce, there were leaders who believed it would never be any bigger than the catalog business, there were leaders that believed it would never be profitable.
