We are quick judging others and situations – making up Elephants just by seeing its tail. And opinions are the simplest of all to have on everything, what counts is what you actually do.
I love Edward de Bono´s book “How to have a beautiful mind” who gives great insights with his methods “Lateral thinking” and “Six thinking hats”.
If we respect and understand each individuals perspective/point of view – where you are coming from, everything would be so much easier and productive.
