If I were to follow this philosophy more often I'd try to be damn sure I knew exactly what I was doing before I did. Going off on your own to do something because you know others would not agree is a bit arrogant. It has to come from a belief that you know more than they do. So if you are going to do something when you know your boss/colleague/co-founder would disagree then you had better make sure you do know more than they do.
