The following was at the end of today's Writer's Almanac piece on Robert Stone and is a quote by him that struck me as rather true.
"Writing is lonely. [...] But most of the time you are in a room by yourself, you know. Writers spend more time in rooms, staying awake in quiet rooms, than they do hunting lions in Africa. So, it's a bad life for a person because it's so lonely and because it consists of such highs and lows, and there's not always anywhere to take these emotional states. [...] It's a life that's tough to sustain without falling prey to some kind of beguiling diversion that's not good for you."
