It's interesting how language/vocabulary changed as well. "I'm upset because I wasn't productive today". When did people get told that their lot in life was to be productive. And who told them to think or talk like that? How did people start to view themselves as machines whose worth is measured by production? Also, where did the "motivation or get motivated" craze come from. All of a sudden, it's "Are you motivated?" or "Get motivated". For what? Why? All of the sudden it's motivation and productivity.
