Someone asked me about what's it like managing 2.2 million associates, and I said, 'When they're Wal-Mart associates, it's not all that hard because of the quality and the depth of our talent.'

I do spend really focused time with my wife, my kids, grandkids, and so when I'm doing something or on a golf course, work has stopped. I'm not always thinking and working... I think a leader has to really be a balanced, whole and healthy person personally in order to be the best leader on the job.

Ibotta represents the future of how mobile technology will be used to drive both in-store and online sales. Not only does Ibotta allow retailers to drive sales directly in store, but it also allows them to see what type of media engagement has the largest effect on resulting customer purchases.

After decades spent in rewrite rooms surrounded by other shouting writers, I discovered that I work best alone. I like being in charge of my time, working out the problems according to my own rhythms and being able to nap. That's a big one, the napping on demand!
