When I was an eager young advertising sales exec working in newspapers in London I was trained to ask prospective clients what were called "open-ended questions". This technique would give me information on their business in order to fully understand their advertising needs and - da-dah! - sell them an ad.
Open-ended questions start with how, why, what, where, when. Stuff like "Where do your best customers come from? What was your most successful advertising campaign?" It's the foundation technique for sales; start with open-ended questions then, as the conversation progresses, narrow it down towards a sale with closed questions which can only be answered with a yes/no response (hopefully), "Do you want an ad?" "Yes, I do".
I had forgotten this gem of ancient sales wisdom until I had a run of clients who had all experienced some form of rejection - from the mummy mafia, a prospective business partner, a romantic interest and from classmates. They were all very upset, and really stuck in their upset. They just couldn't figure it out. Why, why, why would someone treat them this way when all they had shown was kindness/friendship/shared business knowledge/love/support?
Over and over they turned it in their minds, wrestling with the rejection; the sudden cruel "didn't see it coming" rejection. They were all very miserable indeed.
For most the rejection had actually happened years and years ago, but yet it was still as fresh as yesterday because they still hadn't figured out the "why". Trying to figure out why had become a habit of thought, why why why has this thing happened to me?
Here's the thing. This endless questioning of the past "Why did he/they/she reject me when I didn't do anything wrong? What did I do to be treated this way? How long will this rejection last?" etc, are all open ended questions, but asking them of ourselves can only mean we go round in circles.
