If you interview five people about the same incident, and you see five different points of view, it makes you know what makes history so complicated. Something doesn't just occur. It's not like a scientific event. It's a human event. So the dimensions of it will be seen differently by different people.

People tease me about knowing somehow that Obama would put Clinton into the cabinet, and everybody would talk about a team of rivals.

all through my childhood, my father kept from me the knowledge that the daily papers printed daily box scores, allowing me to believe that without my personal renderings of all those games he missed while he was at work, he would be unable to follow our team in the only proper way a team should be followed, day by day, inning by inning. In other words, without me, his love for baseball would be forever incomplete.

You can be enormously effective for a period of time, because it's almost like there's an engine in you that needs to keep going, and you have a greater drive than other people - who may be more happy and balanced in life - because you have to keep going out and proving yourself over and over again.

One of the important qualities that I think is often overlooked is just energy. It's vitality, and sort of a life force that some people have and others don't. Probably that is connected to a love of whatever it is that they're doing. Another quality that I think is central is confidence. Again, some people are more blessed with that than others.

I think some people who go into public life, if they go in needing the applause of thousands, they're never going to work out successfully in the end, because they don't know who they are apart from the crowds.

Good leadership requires you to surround yourself with people of diverse perspectives who can disagree with you without fear of retaliation.
