Life's drama rehearsed

I am not sure whether there are people who are completely detached from themselves.
Someone who sees her/his self from a completely objective viewpoint. Human being has been found to be an emotional creature. Influenced by emotions more than logical thinking. Every person is totally interested in themselves, in some way or another. However much we try to articulate otherwise we remain interested in some sort,to our true self. This has made negotiation more unpredictable and in requisite of specials negotiation gifts that lead to a compromise.
As for me, due to this realisation I would outline below the actions that I would countertake when thinking,relating to other human beings.
I would constantly remind myself that no one has my interest at heart thus I must find out their truest interest that I could use to get mine met. Acknowledge that no one owes me anything and I should wake to smell the coffee. Remain a listener,
a questioner while in negotiation. I would not expect people to like me but would make them like me by being in their side of thinking. Never be afraid to think differently even when it appears costly. Remember that people would be critical of me thus I must remain firm in my views.
It's the drama that each one us rehearsed as per our scripts or others'. The scripts that we run through our minds when in our shell, unconsciously,reviewing our recent,past experience or thinking about our long term goals.
