Your presumptions baffle me. They seem to be the projections of a misanthrope which I seriously doubt you are. Why would someone think their maximum happiness would be achieved by totally disregarding others? Duty, honor, character, responsibility, trust, and sacrifice, I can assure you, are essential to my happiness. Why? Because they assist in the establishment of satisfying relationships with others. And I enjoy others. Even through disagreements like we may be having now -- sometimes especially through contentious debate.
But your "wide open" statement tells me that if any of these gets in the way of your pursuit of happiness, they're discarded like yesterday's newspaper.
