When I criticize somebody else, I am saying [at least] three things - 1] There is something wrong with you or what you did. 2] I am better. I don't have that flaw. [Otherwise, I would be embarrassed to say anything to you]. 3] I am more morally aware than you and while you don't have the capacity to understand what you did wrong [otherwise - why do I need to say? You figured it out yourself] - I do.
So it is simultaneously a lack of humility on my part and a degradation of you.
Criticizing is a good thing to stop doing this year.
