When people learn to listen, people know how to act.

Depending on how you were trying to state this, but most people are more defensive than they use to be. Life is more stressful and in the fast lane that we forget to relax. I was a person who acted before listen until I disciplined myself to do the 1,2,3 breathe and speak. I found the only person who stresses me is me.

if people learn to listen they would know that one line discussions are not profitable and will add more content to their discussions like at least some experience to add to their one sentence to make it more valid
