If your sales feel unpredictable—like some weeks you’re on fire and other weeks you’re staring at your inbox as if it owes you money—there’s a reason.
It’s rarely your effort. Rather, it’s usually your perspective.
Sales don’t generally fall apart because you “said the wrong thing.” They fall apart because you’re solving the wrong problem.
And that’s why it’s time to talk about something that quietly sabotages sales more than any tactic, tool, or trend ever could. I call it The #1 Deadly Sin of Sales.
And it’s this: Failing to think like your client.
This one mistake impacts everything—from your outreach and conversations to your discovery questions, follow-up, closing, onboarding, and even referrals.
If sales has ever felt hit-or-miss… or if momentum has been hard to sustain… or if you’ve found yourself doing “all the right things” with inconsistent results… There’s a good chance this is why. Because sales is not a shot in the dark.
Sales is a strategy. And strategy starts with understanding how your client actually thinks.
Why This One Mistake Is So Dangerous
Not thinking like your client doesn’t usually look dramatic or obvious.
It shows up quietly:
- Messaging that sounds right but doesn’t land
- Discovery calls that skim the surface
- Offers that make sense to you—but not to them
- Follow-up that feels awkward or forced
- Prospects who seem interested… then disappear
When you don’t truly understand what your client is feeling, fearing, prioritizing, or trying to solve, you end up guessing.
And guessing leads to:
- Hit-or-miss results
- Missed opportunities
- Selling to the wrong people
- Wasted time and energy
- Inconsistent revenue
You may even be shooting yourself in the foot without realizing it.
That’s why I say this so plainly: Sales is a strategy, not a shot in the dark.
If you don’t understand your client’s thinking, you can’t connect the dots consistently. And consistency is how sales become repeatable, scalable, and predictable.
A Rom-Com That Nails Client Thinking (Seriously)
There’s a Hallmark rom-com I love called The Pumpkin Pie Wars. Two rival bakery families. A long-standing feud. And, of course, their adult children: Casey (an accountant) and Sam (a baker), who are supposed to hate each other.
At one point, Casey hears second-hand that Sam told his mother he isn’t interested in working with her. Cue the classic rom-com misunderstanding. Except… something different happens.
Casey doesn’t assume. She doesn’t project. She doesn’t spiral.
Instead, she asks him. (Imagine that! Casey actually asks Sam—what the heck?!) She goes directly to the source and says, essentially: “Help me understand what was really said.”
Turns out:
- Context was missing
- Assumptions were wrong
- The partnership—and the relationship—stays intact
That one clarifying question changes everything.
That’s Client Thinking in action. Not projecting. Not guessing. Certainly not filling in the blanks with fear or hearsay. Just clarity.
So… How Do You Actually Start Thinking Like Your Client?
The answer is almost painfully simple: You ask them.
Not your assumptions, not what you think should matter, not what an AI tool guesses based on scraped data. You go to the source.
If you want to understand how your clients think, feel, decide, and buy—there is only one place to get that information: Your clients.
Yet this is where many business owners quietly commit the #1 Deadly Sin of Sales over and over again.
They:
- Hear one comment and treat it as universal truth
- Project their own motivations onto clients
- Use generic language that never came from a real human
- Outsource their thinking instead of listening
Garbage in. Garbage out. Client Thinking comes from listening, not guessing.
Start With What You Already Have
Before you create anything new, look at what’s already in front of you.
1. Reviews
Google. LinkedIn. Facebook. Anywhere clients have shared their experience working with you.
Pay attention to:
- The exact words they use
- What they emphasize
- What surprised them
- What mattered most
Not what you wish they’d say. What they actually said.
2. Testimonials (Especially Video)
If you are not collecting testimonials—especially video—you are missing one of the most powerful Client Thinking tools available.
A testimonial is an exit interview.
It tells you:
- What life or business looked like before working with you
- What triggered the decision to change
- Why they chose you
- What the experience was really like
- What results showed up quickly
- And what life or business looks like now
Only your clients can tell you this. And they will—if you ask.
What You’re Really Listening For
When you review testimonials or interview clients, you’re not just collecting praise. You’re looking for patterns:
- What problem were they trying to solve?
- What finally pushed them to take action?
- Why did they decide to work with you specifically?
- What mattered most in the decision?
- What changed because of the work?
- What does success look like now?
This is your client journey, in their words. No projecting, no polishing, no filling in blanks.
A Real Client Example
One of my clients came to me convinced they understood their client thinking. Sales, however, felt like an uphill battle. When we analyzed their reviews and testimonials, something became immediately clear:
The thing they thought mattered most to their clients… didn’t matter at all. Not even a little.
So we restructured:
- Their first conversations
- Their intake questions
- Their discovery process
We identified:
- The true #1 motivator
- The #2 and #3 influences
- And how each one shaped the buying decision
Once they started asking the right questions—in the right order—everything changed. Sales picked up quickly. Momentum built. Consistency followed.
They now have a repeatable, scalable sales process and are positioned for significant growth. All because they stopped guessing and started thinking like their client.
One Simple Action You Can Take This Week
If you want to start fixing the #1 Deadly Sin of Sales right now:
- Review your testimonials and reviews
- Highlight exact phrases your clients use
- Notice what they emphasize
- Identify what truly drove their decision
If you don’t have testimonials yet? Go get one. Ask a past or current client for 30 minutes. Record the conversation. Listen carefully.
This single habit will change how you sell.
