I see it like a scale of how easy it is to deal with a problem. The easiest thing is to stew and do nothing. Next easiest thing is to is to sit around and complain. After that comes actually doing something about the problem. I think efficient, productive, optimistic people are people who don't have the ramp up time of stewing and complaining, and it becomes self perpetuating: they have a better life that's easy to be optimistic about because problems get solved by themselves without issues ("complaints").
