What I think I've learned is that you're never going to get it all right, and you can't obsess about having a fact wrong or a date wrong or something like that, as long as you tried as best you could. If you've done the kind of research that you're sure is pretty good, then you just have to have confidence in it, so that nothing is perfect in life. I think that is what the criticism has helped me to understand.

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.

Whatever it is that you do, if you have that passion and desire for it, that's the most important thing.

What I learned, more than anything, was that you can't have it all balanced perfectly at any one time. When I was young, it was much more balanced toward work. When I had my children, it was much more balanced toward love and family, and I didn't get a lot of work done. So you can't ask of it to be perfectly balanced at any time, but your hope is, before you die, you've somehow had each of those spheres come to life. That's probably more important than success in any one of those spheres alone.

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.

The past is not simply the past, but a prism through which the subject filters his own changing self-image.

I still think about that one Jamiroquai video a lot.
