You know the one thing that's wrong with this country? Everyone gets a chance to have their fair say.

I figured if I could get really good people who were going to be able to have a big impact in the world over the next decade to come together once a year for ten years and actually sign a pledge to take action themselves, if we did that every year for ten years we could do a lot of good in the world. That's the difference between my meeting and any other. If you don't want to promise to do something, don't come to my meeting, stay home.

The country is groaning and moaning and screaming for change.

Nothing big ever came from being small.

If you believe in a security strategy - a strategy of more friends and fewer enemies, a strategy of greater cooperation and a strategy of keeping America better at home as we grow more diverse - we have to build the minds and hearts to build this kind of world.

A significant number of petroleum geologists believe that we will reach the global maximum of petroleum extraction within this decade or that we have already reached it. Peak Oil happened in 1970 in America, when over half of our oil that we gained from the soil was exhausted ... This is very disturbing, regardless of global warming.

Only a fool does not look to explain his mistakes.
