Learning to "deal" (as in transactions with business / monetary value) is fraught with having to go through emotional hammering. Well, "dealing" in personal life and relationships is not any easier also.
Suppose you go into a negotiation where you are squeezed out. The other party holds cards which impact your long term return. And the party knows that. Then, during intermediate level milestones, they wring you out by getting leverage on those Ace cards. You know that they are dealing it all unethically and unfairly. You cringe under your skin, your blood boils, your eyes want to turn daggers. And yet you let it go. You let them do the unfair thing. Let them bite into you and hold your head feigning dignity while in reality you have been shafted hard from behind. You grind your teeth and bite the steel. All for what? To protect your long term interest.
Can there be a time where loss of dignity or accepting grossly unfair intermediate negotiations becomes unbearable and one walks off the table giving damn to the longer term interest? How much is your stomach to digest all that is coming your way while concentrating on that fuzzy future pay-off? Do you take the call to tighten up your spine even when you know that you don't call the shots on this one? Do you bide your time for evening the score when you get an upper hand?
I am learning the hard way to hide my emotions when I get shafted like this. Probably I add a little more to the pleasure of the other party when they see me seething but unable to act upon it. Its tough to walk away with an air of dignity after getting looted. What do you portray - "it does not matter to me", "it shows what is your character and suits you well", "this is a trivial amount for me; I put it in your bowl as charity and I pity you that you squabble for such amount"? Or do you portray - "I am a good loser, hats off to you for playing this one to the 'T'"?
Grind, grind, grind my teeth. But unable to walk away from the negotiation. Longer term interest is the dangling carrot. Should I learn start playing poker and learn the black art of bluffing the other party into believing that I have a better hand than theirs? Lamentably, I mostly deal with open cards. And that is not how this game is supposed to be played.
