I find people to be people everywhere. Everyone wants the same thing - be successful.

When I got to GM they were using a matrix method of management which means everybody has more than one boss. I first heard about that system many years ago. It's supposed to help with collaboration, but my assessment is that it's pretty hard to get geared for action that way.

I was brought in by the White House as GM's chairman in 2009, around the time of the bankruptcy, and became CEO later that year. As a company, we were grateful for the government's support. But as GM's financial health began to improve, I could detect no real sense of urgency, or even interest, on the part of the government to relinquish control.

When I went into GM there was a lack of morale. The company had gone bankrupt and the people who worked there were embarrassed. Underneath all of, though, there was a will to show what they were capable of, but nobody knew exactly what to do.

At AT&T, I learned an awful lot about people, and how important it is to have the right people in the right jobs. And when I say 'right people,' I'm not talking about their college degree or work history; I'm talking about things like bearing - How does this person interact with other people? Can he or she talk to you and not tick you off?

TARP is funded by taxpayers, so there are many rules about how that money can and can't be used. The result: GM spends an awful lot of time checking in with the people who administer TARP over everything from hiring to executive compensation and management. For a global company, that adds up to a lot of distraction.

Be willing to step outside your comfort zone once in a while; take the risks in life that seem worth taking. The ride might not be as predictable if you'd just planted your feet and stayed put, but it will be a heck of a lot more interesting.
