Chose your company with care, that’s what the wise people say again and again. I am a big advocate of this theory.
I have seen people, overconfident about themselves making a perfect fool of themselves by one sentence spoken, and their arrogance stops them from shutting up, they keep talking till everyone is confident that he is an arrogant fool, which he might not be in reality, he just opened his mouth in the wrong place, in the wrong manner.
I have seen ordinary people elevating themselves to a higher level, and degrading themselves to abyss, because of the company they chose. Being an ordinary person I try to be cautious of the company I keep. I am after all not Jesus Christ or Buddha, I have to be aware of slip and fall.
