 Well, I think one guide to what's exciting is what's in the popular press. If you read Science Times or Scientific American or Sky and Telescope or a lot of other things that are written for the general public, you'll see what's really exciting. And you could say, well, okay, they're working on genetic engineering over there or they're working on building a new telescope over there. I'd like to work on that. All you have to do is say, I'd like to work on it. And somebody will say, oh, okay, come work on it. So then you just have to find a path to get to the place where you want to be. One very famous public scientist is Neil Tyson in New York, and he read Scientific American and he looked to see where did all those people that wrote Scientific American articles go to school. Okay, I want to go to school there. That's what he said. So it worked for him. So it can work for anyone.
