The feeling is, you know, it is really exhilarating, it's like some kind of serotonin rush in your brain, you know, and you really feel great, and you want to go on and do it again, and again, and again. Later on you'll probably change your mind about it, about how well you succeeded. But at the moment that you finish and you're satisfied or you're more than satisfied, that's an extraordinary feeling, and that feeling is so powerful, that it makes you willing to go through the process and the frustration of trying to write again, write anew each time, just to get to that feeling, because there's a lot of frustration before you get there. But the feeling is good, and the act of creation is very pleasurable on a physical level.Paul Simon (2007)
Excerpt from "The Songwriting Process," an interview segment included with the album "iTunes Originals - Paul Simon."
This struck me as a really cool explanation for why I do a lot of things. It's pleasurable to solve problems. It's pleasurable to experience new things. It's pleasurable to read a book and find out how it ends. It's pleasurable to read a book or watch a movie that you really enjoyed the first time again, even though you know how it ends. There are lots of pleasurable things (or maybe not, if this is true, which I think it is - as Fiona Apple replied to a guy in her song "Paper Bag" who said "It's all in your head" -- "so's everything!"). Even finishing a blog post gives some kind of serotonin rush, albeit a very tiny one (judging from my recent low rate of repeating this behavior).
