And as a URL very establishes scientists. How do you balance your life, in terms of, you spend a lot of time single-handedly writing these great textbook, you are running a pretty sizeable lab. And then you also have your family, I heard your daughter got to a great university. How do you sort of keep your sense of balance? >> Well, it's a challenge. It's, everyday you run out of time doing things. >> Do you have a sort of a short list of how all of this classes can be shortened? >> Yeah, that's quite important and also sometimes you get too stressed, so many things. But actually we write down the list. At least it's finite. And also, in writing down the list, you know which one is the most important. And it's actually a lot of, release your anxiety, actually derive some fun. Cross your list. This is done. This is done. This is done. So, organization is important. Also, I mean in terms of balancing all of these, I think that I'm lucky that I have a pretty good lab. Even though my lab is relatively big. A lot of students are very self-motivated and self-sufficient, not only technically but also intellectually. Even though my advice still helps them, a lot of them can be quite independent, so I don't have to spend as much time in details. Although I still would wish I can spend as much time as I can. >> Doing experiments yourself? >> No, no, doing experiments myself is a fantasy now, but at least looking at together with them the original data and discuss detailed experimental design. >> And so with your being a well-established investigator now, what is your advice for the more junior faculties? Imagine going back in 1996 at Stanford, what we would do is something different or more improve of fraction. That could make your size, make everything else a little bit better. >> Yeah, again I give the same advice as I, you just asked me about who my lab members. That I feel you, your single most important focus, as a junior faculty, is to do good science, okay? Some people overly, spend overly time to do other things, like getting a lot of money, writing grants, or networking, all of those things. I mean, they are all important, useful. But I think in the end, what, to be successful is one of the single most important characterized things. What you have done? What have you contributed to science? And then you focus on that, of course you need the money to do science. If you have enough money, don't ask for more. Don't spend more time. Get something done and then more money will come, more easily. >> That's really good advice. >> Yeah. Well, with our time limit, we really appreciate this opportunity that you are giving us advice and talking about the career choice that you made, and then how you motivate you to write this book. And so, thank you very much. >> Yeah, you're welcome. It's my pleasure. I hope this useful to the students of your class. >> For sure, okay.
