Money is not the only answer, but it makes a difference.

I'm not the strapping young Muslim socialist that I used to be.

I do think that saving the economy was a pretty big deal. We did a lot of stuff early that ended up having an impact. I believe that the work we've done in moving our energy future in a cleaner direction is going to stick even if some of the individual steps that we took are reversed by future administrations. I think that it's embedded itself in the economy.

One of the things that I've learned, and I think we've all learned, is that we are not going to get the kind of decisive, permanent victories in this fight against terrorism that we would get from fighting another country. We're not going to get that MacArthur/Emperor moment, because by definition, even after decimating Al Qaeda in the Fata, even after taking out [Osama] bin Laden there's still people there who have both the interest and the capacity if we don't maintain vigilance to strike against the United States.

I know many of you are hurting and angry about the economy, and I don't blame you. It's the worst economy since the Great Depression. When consumers can't buy and businesses won't expand for lack of customers, the government has to be the purchaser and employer of last resort. We learned that in the Great Depression, but Republicans obviously didn't - and they've blocked every jobs program I've offered.

I think that we've had an economy that's been out of balance for too long. So the general principle of raising taxes on higher income Americans, like myself, and providing relief to those who haven't benefited as much from this new global economy, I think is a sound one.

The conversations have been cordial. [Donald Trump] has been open to suggestions, and the main thing that I've tried to transmit is that there's a different between governing and campaigning, so that what he has to appreciate is as soon as you walk into this office after you've been sworn in, you're now in charge of the largest organization on Earth.
