Each of us has a vision of good and of evil. We have to encourage people to move towards what they think is good... Everyone has his own idea of good and evil and must choose to follow the good and fight evil as he conceives them. That would be enough to make the world a better place.

Sin, also for those who don't have faith, exists when one goes against one's conscience. To listen to and obey it means, in fact, to decide in face of what is perceived as good or evil. And on this decision pivots the goodness or malice of our action.

Some cultures believe a long life brings wisdom. I'd like to think so. Perhaps, part of that wisdom is to recognize some of life's baffling paradoxes such as the way human beings have a huge propensity for good, and yet a capacity for evil.

Some people don't like change, but you need to embrace change if the alternative is disaster.

As I look across our company, we have everything from store associates to supply chain associates. Of the 2.1 million people (globally), something less than 75,000 of them are home office jobs. All the other ones are working in a store, a club, a distribution center. And I think those jobs change more gradually. We are still going to want to serve customers and members with people. The change as it relates to the home office jobs probably happens faster.

One of the biggest areas of change in the last decade is related to associates that work in our stores, picking orders for delivery and pickup for our customers. And we have something north of 200,000 people doing that job, and yet we have about the same (total) number of people working in Walmart U.S.
