If two scientists are giving their papers at a symposium, and one of them is just naturally better at talking to the public or talking to a group of people, that scientist is liable to get more attention - in fact, I'm told that they do get more attention - than the one who's a little more stiff about it. Well, that's not good for science.

There is a wonderful feeling of power when you're a director, but I don't think I need that, and I'm OK without it.
