My father Tom was a workaholic who never missed a single one of my sporting events for nearly two decades, and imparted in me a sense of risk and adventure. Being the one in the middle, I had more room to drift, and after college, I left the U.S. for Chile.

I have interviewed Hugo Chavez, Tim McVeigh, and hundreds of fascinating characters in South America, where I have lived for the past 15 years.

It is a gift to be a teenager, and I see a dad's job as lifeguard, not chaperone.

I would like to be remembered as the reporter who snuck back stage to all the off-limits shows, be it the Vatican dressing room, the Pentagon war room, or the Celtics locker room. Some curtains ought never to be pulled back; others deserve to be ripped down. When appropriate, I want to be the curtain remover.

The language 'It's too late' is very unsuitable for most environmental issues. It's too late for the dodo and for people who've starved to death already, but it's not too late to prevent an even bigger crisis. The sooner we act on the environment, the better.

Art should not be a tool of politics, but sometimes art can help make the political climate more open and help society become more free.
