I have said that I'm not running and I'm having a great time being pres — being a first-term senator.

This is a moment in history where it is almost hard to catch your breath.

We are at a stage in history in which remolding society is one of the great challenges facing all of us in the West.

I try to schedule at least one day a week to catch up, to feel like I'm breathing again. I take vitamins. I have a treadmill and weights at home, but I prefer walking outside, just kind of breathing and letting it all go. I try to read for pleasure whenever I can - it's a great way just to shut it off for a while so your brain doesn't get fried.

We are not putting ground troops into Iraq ever again. And we're not putting ground troops into Syria. We're going to defeat ISIS without committing American ground troops.

It is important to learn how to take criticism seriously, but not personally.

When I was secretary of state, we actually increased American exports globally 30 percent. We increased them to China 50 percent.
