In time and with water, everything changes.

The stores are an asset, and they have a great assortment in them and they're close to people. Being within 10 miles of 90% of America is a huge advantage, especially with fresh food at a good price. But we must also, if you think long-term and you think about what the company wants to accomplish, you must have a big and important first-party e-commerce business, and you must have a marketplace, and the things that go along with the marketplace.

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.

Wise and prudent men - intelligent conservatives - have long known that in a changing world worthy institutions can be conserved only by adjusting them to the changing time.

Businesses grow and they don't change enough and they decline over time. Retailers do that on a bit of a faster cycle.

If you treat people right they will treat you right - ninety percent of the time.
