The rich invest in time, the poor invest in money.

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.

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.

There seems to be some perverse human characteristic that likes to make easy things difficult.

Whatever you like to do, make it a hobby and whatever the world likes to do, make it a business.

The value of a business is the cash it's going to produce in the future.
