I hate protocols in life

Whenever I do something in the way I enjoy the most, I find a lot of people running over to me, speaking of protocol violation. Who made these rules? I never understand. Rules are for good. Rules are for happiness. Then why should we frame rules that hinder happiness. Even when I am doing my job, I feel the only rule necessary is to do justice to the work assigned and do it properly. How to do justice, How to make it proper are all matter of individual happiness and sense. Then why should everyone say, you shouldn't do it this way or that way?
