I was wondering where Greg had gotten to; turns out it’s a Black Dog issue. Glad to see you back, Greg, and don’t apologize for taking time off. Ya gotta do what ya gotta do.
He also points to a possible source for the Black Dog metaphor: Winston Churchill. I didn’t have any idea that Churchill was depressive, much less that he used this analogy, but I dug deeper and found a book about it:
Churchill’s Black Dog, by Anthony Storr, a series of essays on the success of creative individuals and their motivations.
