For 14 years, author Lee Jae-hee was the nation's number-one salesman. Then he quit — and the shock set in. The moment his mid-sized company's logo vanished from his business card, the phone went quiet, and everywhere he went he was treated like a door-to-door peddler. It was a painful realization that his glittering title had never been his own ability — it was the halo of the company standing behind him.

But this very crisis is what forged his real sales skills. So what are the three survival systems that kept him standing without a corporate banner over his head?



A Mental System That Doesn't Crumble Under Rejection

In the past, a single "No thanks" was enough to break him. This time, Lee began to read rejection differently. Rejection, he decided, wasn't a denial of who he was — it was simply a refusal of what he was offering.

The more fundamental shift was positioning himself as an expert. Instead of showing up as just another salesman, he led with, "I'm here to diagnose your logistics problems" — and the other side's whole attitude changed. He even had a uniform made to make that expertise visible, and it paid off.

This is the heart of personal branding. Only when you compete on your own expertise — not on someone else's corporate banner — does your real ability come through.

The Power of the 70/30 Listening Rule

For the author, the key isn't talking — it's listening. Lee's iron rule: let the other person speak 70 percent of the time, and hold yourself to 30. Stay quiet, and the customer will eventually open up about what's really going on. That, he says, is what experience taught him.

An interesting discovery: relationships with your own colleagues matter just as much as those with outside customers. When there's an urgent order, a return to process, or an approval that needs pushing through, it's people — not systems — who ultimately clear the bottleneck. That's why, in B2B sales, the goodwill of the people doing the actual work matters as much as that of the decision-makers.

On the surface it looks like a deal between two companies, but in reality it's trust between people that decides whether the deal gets done.

Letting AI Handle the Busywork So You Can Focus on People

Just as one marathon champion named "a grain of sand in the shoe" as his toughest opponent, what truly wears a salesperson down is the busywork. By putting AI to work, the author cut the time it took to write a proposal from three hours to thirty minutes.

The real question is what you do with the two or three hours a day you free up. His answer: "Spend it looking your customer in the eye, sharing a meal, and actually listening to their story." The whole point of chasing efficiency, in the end, was to buy more time with people.

The more technology advances, the more valuable human contact becomes. The survival strategy is to pour your human energy into the things AI can't do — trust, empathy, and building relationships.

Real Skill in an Age Without Banners

His experience is the reality many working people now face. In an era where the idea of a job for life has disappeared, the company banner can be taken away at any moment. What's left when it goes is nothing but your own real ability.

So what is real skill? It's the mental toughness to withstand rejection, the ability to listen to the person across from you, and the sense of balance to use technology as a tool while keeping your focus on people. It isn't a dazzling résumé or an impressive title — it's the power to build trust and forge relationships even in the middle of a crisis.

"Leave the technical work to AI, but we ourselves must always turn toward people." This one line from a 14-year sales champion captures the essence of survival in the age of AI.
