I spent my whole life in the private sector, 25 years in the private sector. I understand that when government takes more money out of the hands of people, it makes it more difficult for them to buy things. If they can't buy things, the economy doesn't grow. If the economy doesn't grow, we don't put Americans to work.

If I have a bad hair day, I just think, Well, it will be an OK hair day tomorrow. Just put your head down and go. Life is a bit like being on a roller coaster, which is, You get on and there's no stopping along the way. There are some days when you feel like this is pretty tough, and there are the days that are exhilarating, but you just keep on going.

A Pakistan that falls apart, becomes a failed state, would be of extraordinary danger to Afghanistan and to America.

My policy on energy is... to make America the largest energy producer in the world. I think we can get there, in 10 or 15 years. That will bring back manufacturing of certain high-energy intensive industries. It'll bring back jobs. It'll create a surprising economic revitalization of this country.

If I'm president, America will be very strong.

China has an interest that's very much like ours in one respect, and that is they want a stable world. They don't want war. They don't want to see protectionism. They don't want to see the world break out into various forms of chaos.

What you believe, what you value, how you live - matters.
