As I head into the Thanksgiving season, I am, like many people, trying to cultivate the value of gratitude. The problem is that Thanksgiving is arriving at an inconvenient time this year when a lot of things seem to be going wrong with health, finances, blah blah . . . I won't bore you with details. But when it's a challenge to be thankful, I turn to the most thankful person I know. Who is not actually a person.
