When you are negotiating with your husband about what responsibilities he agrees on as his own, be sure to think about his strengths. Have him pick responsibilities that have challenges he knows he can meet.
Just like a job title. If a husband knows what his job description is up front, he is sure to have an easier time of it. Knowing and doing exactly what his brain has eventually trained him to do on a daily basis has to be much easier than regularly fighting with his wife because he has no idea what is expected of him.
