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.

AT&T will not block access to the public Internet or degrade service, period.

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?

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 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.
