Then you know that he can be stubborn in a very good way. ;)
I read a best selling book years ago by a man who had a serious medical problem that was supposed to kill him and was put in a hospital and he had his bed moved from the hospital to across the street in a hotel and hired a nurse to do what he needed - he would not stay in a hospital - he preferred his own place so he had control over what happened and what his diet was. He lived for years after that. Taking control of what happens to you gives one a much better chance of living a productive life.
Jim's independent thinking and doing, taking control, makes him a super man.
