My goal in coming to General Motors was to help restore profitability, build a strong market position and position this iconic company for success. We are clearly on that path.

I'm a pretty average guy and want to keep a low profile. I don't want the world necessarily to know about me.

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.

I started at GM knowing very little about that particular business. Not being an expert means you have to learn everything, starting from the basics.

I've been accused many times of not talking very much, but I guess I don't believe in talking things to death. You can talk too much on most anything and it stops being productive. There is a time for action. Eventually you have to pull the trigger.

Find your passion is in life, and do what you can to integrate that into your work life. That's not to say you won't have occasional frustrations in your job - that just goes with the territory - but at least you'll feel better inside, and that, over time, will mean more to you than you might think.

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.
