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.

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.

So long as TARP money is wrapped up in GM, the company will never shake its 'Government Motors' image. That label, as competitors and GM employees are keenly aware, is code for one thing: 'GM is a failure'.

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.

No partnership between two independent companies, no matter how well run, can match the speed, effectiveness, responsiveness and efficiency of a solely owned company.

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.

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?
