In chapter 6 of “Predictably Irrational”, Dan Ariely discusses a problem every student is familiar with, procrastination. You have an essay to do yet here you are browsing through facebook, looking at pictures of strangers and comments from people you don’t like. You know you should study but you could watch one more youtube clip. Every night you promise that the next day you will work hard and study, yet you never get around to it. You promise that you will exercise and eat healthy but end up sitting on the couch all day eating pizza.
