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

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.

None of us has control over the economy, the job market, or anything else in the global sense. But we are 100% in charge of how we respond to challenges that come our way, be it the loss of a job, a career derailment, or some other disappointment.

I don't know anything about cars. A business is a business, and I think I can learn about cars. I'm not that old, and I think the business principles are the same.

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.
