Not a long time ago, I learned a valuable lesson from my father. 

There was a celebration at home and some friends of my parents were invited. 

As we were having dinner together some background music was playing. 

My father’s friend said: “Oh this is Pink Floyd I really like this song”

I knew he was wrong. I knew that, I knew it positively. There couldn’t be the slightest doubt about it. And so, to get a feeling of importance and display my “superiority” I had to correct him.

He angrily replied “I’ve been to a Pink Floyd concert so I know it’s one of their songs...” 

My father, sitting between us said: “Pablo you are wrong, it’s Pink Floyd”

When they left, while we were cleaning up, I asked my father… “Dad, you knew that was Led Zeppelin” “Yes, of course,” he replied, “Immigrant Song from their 1970 album... But son, Why prove a man he is wrong? Is that going to make him like you?”...

I’ll always remember that lesson

For that reason, here’s the key to win every argument in less than 10 seconds: Don’t argue

I’ll repeat this because it’s important: The only person that wins an argument is the one who doesn’t argue. 

You can’t win an argument. You can’t because if you lose it, you lose it; and if you win it, you lose it. Why? Well, suppose you win. Then what? You will feel fine. But what about him? You have made him inferior. You have hurt his pride. He will resent your triumph. And always remember… 

"A man convinced against his will, is of the same opinion still."
