Winning an argument solves nothing. It has no advantage in life apart from self validation and ego boosting. Self praise is meaningless.
Getting someone to understand your point of view because you articulated your points systematically and with diplomacy, is a great feat indeed.
You don’t have to be right. What you’re doing here is expressing yourself well enough for another person to understand your point of view. This opens the door for advancement.
Go point by point. Dont overwhelm.Talk and listen. Most of communication is really about tone and body language. It’s easy to miss the message if your tone and body language are confrontational.
