Would the increase in productivity not happen to almost all people if they were given the interesting work and the direct support of a good leader to help them focus? At least, I feel a difference like night and day when working on things I am interested in, as opposed to when I am doing chores. This includes thinking about the problem when I am on the toilet, during sports, on walks, on the bus, and so on.
