Proper manners and proper English will open many doors on the journey to success. The fool doesn’t get this. Although we would love to think that it is evil to “judge” in real life we judge everyday, all day. Some for the sake of haughtiness, others to make safe decisions, still others to hire the right person.
Even so I have many young friends who believe that the world is going to bend to their wishes and allow them to behave as they please. Then they get fired or passed over. But instead of facing facts and reviewing the outcome they create an excuse or two. Our greatest adversary will always face in the mirror. Start with that guy.
