"As I look back now I wonder how I was ever able to sell anything. I lost years of my life in scrapping and arguing.I keep my mouth shut now.It pays."
As wise old Ben Franklin used to say："If you argue and rankle and contradict, you may achieve a victory sometimes；but it will be an empty victory because you will never get your opponent's good will."
So figure it out for yourself. Which would you rather have, an academic, theatrical victory or a person's good will？You can seldom have both.
