Degree of Stupidity

When someone have to beg somebody for his right, and still didn't get it.
When somebody still keep on taking something that he never like, again and again and again.
When someone keep on doing something useless, and he know it.
When something is not happening the way we expect again and again and again and it is because we keep doing it the same way.
When we keep losing in the battle that we could never win.
When we keep paying for something we never agree to pay. Is it a matter of stupidity? Or there's something else... Something about us that we didn't understand?
