Eric Liu: Have you ever thought about like drawing the line? At what point would you just say, okay, not worth it? Like I know you and Laurie haven't been able to do as much traveling as you'd like for various reasons. But are there things that you've said when it comes to this, no way I'm done with this? Liu: Well, one is pretty easy. My employers are so flexible with me and my schedule. If that changed, I would probably bow out immediately because having that freedom is worth everything.
