How do you look at people? Do you look at them with contempt or with a neutral outlook or with admiration? I have seen arrogance/contempt written all over their face, in many people, I have met.
"Contempt ---Neutral---Admiration" scale is a very useful scale.
Another scale that is very useful, is the one, that checks how judgemental you are.
Some people are arrogant and some people are judgemental. However, if you are arrogant and judgemental, then you will be walking alone, all the way, through out life.
We need to be aware, how we affect others.
