Chuck Klosterman said this quote

But-when you really think about it-that emotional support only applies to the experience of living in public. We don't have ways to quantify ideas like amazing or successful or lovable without the feedback of an audience. Nobody sits by himself in an empty room and thinks I'm amazing. It's impossible to imagine how that would work. But being amazing is supposed to be what life is about. As a result, the windows of time people spend by themselves become these meaningless experiences that don't really count. It's filler. They're deleted scenes. pg 156
