 Well, look, that's the fun for you guys, see, and you see the job, to tell you the truth, the job of a teacher is to produce students who are better than the teacher. No, that is the job of a teacher. See, if you produce students who are just as good as you are, here's new progress made, and you want to make progress. The idea is to learn things better. So your job is, yes, I'm going to be as good as this professor, but I'm going to be better. I am going to learn more. I am going to contribute. We know that, but we don't know this, and we're going to find that out. And you just keep plowing away like that, and if everybody does that, then the science gets better, our knowledge gets better, and we all have a heck of a lot of fun. Well, that means fun.
