The shift to a cleaner energy economy wont happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact.

Environmentalism is not an upper-income issue, it's not a white issue, it's not a black issue, it's not a South or a North or an East or a West issue. It's an issue that all of us have a stake in. And if I can do anything to make sure that not just my daughter but every child in America has green pastures to run in and clean air to breathe and clean water to swim in, then that is something I'm going to work my hardest to make happen.

As tough as things have been, I am convinced you are tougher. I've seen your passion and I've seen your service. I've seen you engage and I've seen you turn out in record numbers. I've heard your voices amplified by creativity and a digital fluency that those of us in older generations can barely comprehend. I've seen a generation eager, impatient even, to step into the rushing waters of history and change its course.

It's not a nice-to-have - it's a must-have. It's time we stop treating child care as a side issue, or a women's issue, and treat it like the national economic priority that it is for all of us.

My job is exhilarating. It's challenging. I find that the governance part of it, the decision making part of it - actually comes - comes pretty naturally. I think I've got a great team. I think we're making good decisions. The the hardest thing about the job is staying focused. Because there's so many demands and decisions that are pressed upon you.

I get a thick book full of death, destruction, strife, and chaos. That's what I take with my morning tea.

One of the things that I am concerned about is the degree to which we've seen a lot of commentary lately where there were, there are Republicans or pundits or cable commentators who seemed to have more confidence in Vladimir Putin than fellow Americans because those fellow Americans were Democrats. That cannot be.
