Are you often perplexed by why people do the things they do? Often I oversimplify the reason by simply thinking they are incompetent. I suspect they do not see things the way I do. Often the reasons are hidden from you.
These hidden factors could be simply be things like they could just had a fight with their spouse or a bad review from their boss. I keep reminding myself I cannot see things through their eyes.
After that reminder, hopefully I become more curious about their point of view and listen more carefully to discover what is really going on.
I remind myself that nobody intentionally makes mistakes. If they appear to intentionally make a mistake, I must remember to did deeper.
