I think the most important advice is, a person doesn't have to find out right away. It's not like their first attempt at finding a profession is the only one they're going to find. I might well have gone down other paths, and it still might have been okay. But if you find something that you love, and if it keeps deepening with each new experience, then just stay with it.

I keep thinking that history runs in cycles, and that some day certain large issues will come before the country again. There will be leaders that inspire young people. I don't think it means that it's over forever, but I'm getting pretty impatient.

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.

I've chosen to be a commentator and an analyzer of politics, rather than an actual doer of it. I think it could have gone the other way, but I'm not sorry that it didn't, because this made it easier to be home with my kids and to spend time with them. Writing you can do right in your house. You don't have to go anywhere.

The one thing that John Kennedy did, above all else, was to energize young people to feel that they wanted to give something to their country. I just hope, for young people of this generation, that they'll experience that feeling once again, that by working on large goals, they can do something more than their own individual ambition.

Where's the progress that we're going to see in Afghanistan? You have to keep public support both on the economy and the war or these things will really become troubling.
