So, do I practice what I preach? Pretty much. Having horses ensures that I'm outside doing something physical every day (even when I don't ride there's feeding, grooming, mucking out.) I'm involved in community and church activities; I have friends with interests other than writing, as well as writer friends. I'm homeschooling a teenager (in itself a full-time occupation) and when really upset I take it out on a batch of bread dough. (Bread dough is the only thing I know which gets better the more you beat on it.) Still...depression sneaks up on me every now and then and ruins a story I'm working on, or sucks the life out of a novel. I start feeling frantic, trapped, helpless, hopeless. I can't write. I don't want to ride the horses; I don't want to make bread; I don't want to do anything but brood. When the penny finally drops, and I realize what's going on, and work on it--the depression lifts again, and the writing rolls on.
Cultural effects. One might expect the Great Depression to have induced great skepticism about the economic system and the cultural attitudes favoring hard work and consumption associated with it. As noted, the ideal of hard work was reinforced during the depression, and those who lived through it would place great value in work after the war. Those who experienced the depression were disposed to thrift, but they were also driven to value their consumption opportunities. Recall that through the 1930s it was commonly thought that one cause of the depression was that people did not wish to consume enough: an obvious response was to value consumption more.
