A couple of years ago, I reviewed one of Don’s books, and found it excellent. He reviewed From Depression to Contentment. Recently, he invited me to contribute to an anthology he and his wife are constructing, and has shared a subtly funny story about the coronavirus experience.
He also sent me the transcript of a talk of his on Youtube. I found it to be exactly in tune with my philosophy, so you will approve too.
Do visit him, and let me know what you think.
