There's a guy inside me who wants to lay in bed, and smoke weed all day, and watch cartoons and old movies. I could easily do that. My whole life is a series of stratagems to avoid, and outwit, that guy.
If Bourdain had been satisfied to be that guy, would he still be alive? Maybe not, if being a celebrity chef was a way of running from something that was going to catch him either way.
Personally, I fight and fight to have nothing to do all day, and I always fail, because the world wants stuff from me. That's reason enough to not kill myself. The biggest reason is I have to finish my novel. But I think the most universal reason to keep living is the beauty of small moments. If you look for them, you can find them all over, and think to yourself, I'm glad I'm still here to see this.
