Recently I heard something profound at work. I did not expect it.
"Assume positive intent"
How often do we perceive others as enemies in our mind by viewing their presence or presentation as antagonistic. Imagine all the misunderstands that could be averted and how much brighter the world would be if we had an outlook that our fellow humans were striving towards a positive result just as we are.
Give it a try next time you speak with someone. They may just have a difficult time expressing themselves which could be viewed as negative input. Everyone wants to have a happy and fulfilling life after all.
