Everything in life – and I mean everything – is a negotiation. We negotiate with our bodies: “Ok, I’ll give you a little more exercise if you’ll give me a few more days of healthy life.”
We negotiate with our partners: “I’ll do something I know you like if you’ll do this thing with me.”
We form professional alliances based on mutual trust and respect in an understood (if unstated) agreement of “quid pro quo.” Make no mistake, this is how shit gets done in life. It seems fairly obvious, no?
With humans the very concept of providing a service to the community is a form of negotiation. You get to reap the benefits of being a respected member and the protection of the tribe by being useful.
I don’t think this is either a good or bad thing, it’s just the way life works.
In other words, always try to do the right thing and provide value. This is the best base of power from which to negotiate.
