I don't quite remember how I stumbled upon the too much contemplation video, I think I was googling something about excessive contemplation because of a podcast I was listening to. It used to be a common opinion that excessive contemplation was bad and could cause all sorts of illnesses. I know it's true in some sense, people can get addicted to thinking about how great something will be, and they end up spending a lot of time thinking about it but never really get anything done.
