Choking on Hope as Read by Sam Mitchell of Collapse Chronicles
I’m re-posting the excellent YouTube video of Sam Mitchell (of Collapse Chronicles) reading my recent essay “Choking on Hope.” I humbly ask that you watch the first 5 minutes of this. Sam had me laughing out loud with his proficient choking skills. I promise, he will tickle your depressed doomer spirit. If the first 5 minutes doesn’t hook you, well, that’s okay too.
Enjoy!
