"There is nothing that strengthens the ego more than being right. Being right is identification with a mental position - a perspective, an opinion, a judgement, a story. For you to be right, of course, you need someone else to be wrong, as so the ego loves to make wrong in order to be right."
This might seem obvious, but if one looks carefully how we are interacting with each other, this quote is absolutely true.
I myself go down that road often....
