Nor be over estimated as being necessary or absolutely useful in being successful in sales. I can only speak for myself in that when I went from learning an arsenal of tools and putting them to use to trashing it up and speaking directly from the need/want/willing to buy or do position my business improved and so did those who do the same.
My conversation with prospective buyers has to do with understanding the details, answering and asking questions, and coming to a mutually agreed upon conclusion that usually is a sale. BUT that's understood from the start - not always 100% though.
My conversation isn't to slot in the right close at the right time nor to slip in the right over coming objection at the right time - I don't sell that way.
Having given up over coming objections and slotting in closes which seem to fit a certain situation my sales, my group sales, have all improved as has moral and confidence for those who work this way.
What I'm saying shouldn't underestimated because of learned notions and even experience - going from the subjective to the objective, from the known to the unknown, isn't easy to accomplish even for a moment.
BUT again, I'm an amateur and not a professional - the success I've had comes from that approach and feeling about what I do.
