Together with a culture of work, there must be a culture of leisure as gratification. To put it another way: people who work must take the time to relax, to be with their families, to enjoy themselves, read, listen to music, play a sport.

People need a "Why?". I'm a big fan of Simon Sinek, people need to know why they're doing what they're doing, me included, and they want to work at a company with values and a culture that matches those values and I think that those things matter even in a pure tech company.

There are all these things that add up into this business that's Walmart that keeps it really interesting. At the root of it all, though, it's a people business and it's a merchandising business. Today, it's increasingly a technology business. The supply chain is critical, of course, and real estate still plays a key role.

A culture of high standards is protective of all the "invisible" but crucial work that goes on in every company. I'm talkingabout the work that no one sees. The work that gets done when no one is watching. In a high standards culture, doing that work well is its own reward-it's part of what it means to be a professional.

This sign I give you: every people speaks its tongue of good and evil, which the neighbor does not understand. It has invented its own language of customs and rights.

Most people like working, but they'd also like to have more time with their family or to pursue their own interests.
