Priestley reframes selling as a diagnosis, mirroring how a good doctor works. There are three coordinates: the buyer's current reality, their desired reality, and the obstacles and criteria in the way. The salesperson's job is to map the path of least resistance between the first two by doing exactly what a clinician does, asking many questions, running an assessment or diagnosis, then recommending a treatment plan: do this, this and this to get from here to there. Professionalism, not pushiness, is what people praise: great questions, guided advice, product knowledge, listening and sensible recommendations. This model dissolves the fear of being a 'snake-oil salesman' by making the sale an act of understanding and honest guidance rather than persuasion or pressure.
Origin
Extracted from Deep Dive with Ali Abdaal, given as the mental model to defang Ali's fear of selling.

- 02Professional beats pushy every time.
- 03Diagnose before you prescribe.
- 04You're marrying what they want to what they need.
How to run it
- 1
Map the current reality
Ask a load of questions to understand exactly where the person is now and what's making them unhappy.
Pro tip Listen more than you talk; you're gathering symptoms.
Watch out Prescribing before diagnosing feels pushy and misses the real need.
- 2
Clarify the desired reality
Establish what they genuinely want to achieve, the outcome they're after.
Pro tip Reflect it back so they feel understood.
Watch out Assuming their goal instead of asking leads to the wrong solution.
- 3
Diagnose the obstacles
Identify the obstacles and criteria standing between current and desired reality, then run an assessment.
Pro tip A formal diagnosis or assessment step builds trust and authority.
Watch out Ignoring their criteria means your recommendation won't land.
- 4
Prescribe the treatment plan
Recommend the path of least resistance: the specific steps that move them from here to there.
Pro tip Frame it as guidance, like a doctor's treatment plan.
Watch out A generic pitch, not a tailored plan, breaks the diagnosis frame.
In the wild
A professional speaker walks into an Apple store; the Genius asks what they'll use the device for, learns they use Keynote heavily, and recommends a model whose touch bar shows slides while presenting. The customer feels helped, not sold to.
→ A positive, professional experience that still ends in a purchase, proving good selling is service.
Common mistakes
Pitching before diagnosing
Recommending a solution before understanding the buyer's situation feels like pressure and misses the real need.
Confusing pushy with professional
The word people use for good salespeople is 'professional': questions, guidance and honesty, not aggression.
Is it for you?
Best for
Founders and professionals selling services who feel uncomfortable with 'sales'.
Not ideal for
Transactional, low-touch retail where no consultation is expected.

“essentially you are recommending a treatment plan ... and that's sales”
