Everybody knows politics is a contact sport.

Here's the truth: even if countries like the United States curb our emissions, if growing countries like India - with soaring energy needs - don't also embrace cleaner fuels, then we don't stand a chance against climate change.

Whether our forebears were strangers who crossed the Atlantic or the Pacific or the Rio Grande, we are here only because this country welcomed them in and taught them that to be an American is about something more than what we look like, or what our last names are, or how we worship.

We can't wait for Congress to do its job. So where they won't act, I will.

And I’ve said this all across the country when I talk to parents about education, government has to fulfill its obligations to fund education, but parents have to do their job too. We’ve got to turn off the TV set, we’ve got to put away the video game, and we have to tell our children that education is not a passive activity, you have to be actively engaged in it. If we encourage that attitude and our community is enforcing it, I have no doubt we can compete with anybody in the world.

I've got two daughters and I want to make sure that they have the same opportunities that anybody's sons have. That's part of what I'm fighting for as president of the United States.

One of the thing about being President - that can't be taught, you have to experience, is - there is the sheer weight of decision making. And when I make a decision to send 17,000 young Americans to Afghanistan - you can understand that intellectually. But understanding what that means for those families, for those young people - when you end up sitting at your desk, signing - a condolence letter to one of the family members of a fallen hero - you're reminded each and every day, at every moment, that - the decisions you make count.
