Inner peace is a very important desire for a man who is growing in age and wisdom. I notice how content I can be (me being one of the most ambitious people I know) when I see my wife is comfortable, or my kids are happy. I become stable inside. I guess that is why it is the American Dream.
Often as men we can be hard on our spouses when we do not know what it takes to get that inner peace. We become abusive to the ones who brings us peace, or at least contribute to it. That is why as men we must practice being honest with ours first. Even when you do not like what you have to tell yourself. Your ugly motives and actions, own them yourself first. This will help you learn yourself. Then in return you can teach others how to help you when you need it.
