It's a marathon, not a sprint. I actually feel like I come to work stronger when I've had a little time on the weekend to step away from it and enjoy my family and other things. I come back energized. If people think they're going to work 24/7, week in and week out, they're not bringing their full strength to the table.

I know we're all addicted to our smartphones, and I'll say, if I forget my smartphone, I go home and get it. And so understanding how to integrate that technology into the driving experience, both the front seat and the passenger seat and the back seat, I think is very important.

Connectivity offers a great opportunity for General Motors. When you look at the investment we have made in OnStar and putting 4GLT in and the access you have to not only put data in, and we haven't really tapped into the data you can use from the vehicle.

I started at General Motors at 18 years old as a co-op student at the General Motors Institute, which is now Kettering.

Our goal is to make General Motors the most valuable automotive company. Clearly, that is having sustainable profitability and driving great returns for our shareholders.
