University is a small society. Although not as cruel as the real society, it is almost less. When you understand that you want to succeed in something, you can't succeed only by your ability. You have to have a very extensive interpersonal relationship and a very good background to complete it, or you are rich. Otherwise, nothing can really be done. You want to borrow some equipment you want to use. No one was there. Where can you borrow it? What can you do without equipment? Then there is no ability to show, where are the activists? Without activists, where are you from in party member? When you understand what a cold world is, you must learn how to be an individual and how to be a person that everyone likes. When you meet someone who used to be very nice, don't be so close. You and him haven't changed, and neither of you has changed, but we all grew up in different places and different environments, adapted to society and learned how to be a man.
