I think that people that shop Walmart frequently and love the brand the most find it very natural to come to us first for e-commerce. But for others that may shop around or not have chosen to shop at Walmart in the past, you get what you earn, and our opportunity to earn their business starts with winning their grocery and consumables basket.

The only thing I really think about is: How are we making decisions and getting things done such that Walmart is succeeding and creating value 50 years from now?

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 you can love more than one child, and we've got to do all these at once. I think there's a store inventory opportunity for us and buying and selling merchandise is hard, by the way. There's a lot of people here that have been doing it for a long time and they're good at it, thankfully, but it's not easy.

I think scale matters, and being an Aggregator creates lots of opportunity, but scale also has a lot of disadvantages and it's an imperfect concept.

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.
