When I was a kid, I was a bit of a space geek. I loved the space program and all things NASA. I would read books about our solar system; I had pictures of the Space Shuttle on my bedroom wall. And yes, I even went to Space Camp.

When I present, I cheat. I only talk about things I care about.

If we care about the average working American, then Wal-Mart matters. A lot.

It is like when a player has a slump, we do not trade them, we coach them. It is the same with our employees. The best leaders come to the aid of their people, whose performance is down. Not come down harder on them.

A leader, first and foremost, is human. Only when we have the strength to show our vulnerability can we truly lead.

We all have the luxury of looking out for ourselves. Leaders also have the honor of looking out for others.

A true friend is someone with whom protocol is no longer necessary.
