Because as much as the world loves you one minute, it can be way down on you the next.

I think you can't dip your toe in and dip your toe out. I think either you're in it or you're not.

When you travel with the president, especially when you are traveling to foreign countries, the people that you travel with really become your family pretty quick. ... Most of the people who travel with me, they knew when I would get a stomachache.

When I had been dating my husband for a while, the president Obama said to me, "When is he going to put a ring on it?" And I was like, "Oh, come on. We are so busy. We don't need to think about that." He said, "He needs to put a ring on it because you're worth it." And the thing is, I'm not even kidding you, it was about a week or two later that we got engaged.

The thing that I think is so depressing, fundamentally, about Donald Trump, is that he doesn't appreciate what's happening right now. He doesn't seem to think it's an honor. He doesn't seem to understand why we're actually super blessed to have the government we have. I also don't ever get the sense that he loves Americans.

I would encourage young women to find a person, give it your all, and leave it all on the field. The one thing I have found is that, if you are sitting at a table, most women will want to only give their opinion only when it's almost fact in their mind - whereas dudes will pontificate a lot more. And I will tell you, I've started pontificating a lot more, which is very satisfying. Women should not be afraid to speak.

I saw Obama's thought process behind the few moments of free time he had and how he used them. So, I knew that him taking the time to call me meant he really cared and really deeply understood how upset I was. That's what made it so meaningful.
