I have to do a lot of things and solve many problems every day. I’m so tired and short of time. So, just do something and do more, please! I’d suggest a movie “The Devil Wears Prada”, and you can learn how to be an excellent guy from the movie. I am too busy to answer your “great” questions anytime and anywhere. Don’t make me tired. Please make your own decisions and figure out things by yourself. Try to be a man! All graduate students need to understand and learn it.
