When I first heard that advice, I didn’t quite understand it. In the early days, the idea of turning down money sounded almost absurd.

After all, isn’t the whole point of business to earn as much as you can? But as the years went by, I realized that some opportunities come at too high a cost.

The real expense isn’t always financial. It is the stress, the wasted time, and the energy you lose along the way.

Business has a way of teaching you that growth isn’t just about saying yes. Sometimes, the most important growth comes from learning when to say no.

As Friedrich Nietzsche the German writer and philosopher wisely put it: “Judge every decision by what you stand to lose, not what you stand to gain. Judge it by what it will cost you.” That perspective can change everything.

Take this example. At Brand Experts Kenya, one of our services is professional CV writing. Occasionally, a client comes in wanting their CV revamped, but instead of trusting the process, they insist on dictating every detail.

What they may not realize is that CVs today must be ATS compliant, formatted to pass through Applicant Tracking Systems used by employers. A CV that ignores these standards will likely be rejected before a human recruiter even sees it.

When a client refuses to listen, the end result is predictable. Their CV doesn’t perform, frustration follows, and suddenly the blame shifts back to us. The truth, however, is that the problem wasn’t poor service. It was poor collaboration. And in such cases, the wisest choice is often to step back and let that client go.

The old saying goes, “The customer is always right.” But anyone who has spent enough time in business knows that isn’t always true. Some customers are not only wrong, they are simply not worth the trouble. And the courage to let them go can save your time, your reputation, and your peace of mind.

Not all money is good money. The hours spent trying to satisfy one difficult client could be used to serve several others who value your expertise, respect your process, and allow you to do your best work. Firing a client isn’t about pride or arrogance. It’s about protecting your standards, your energy, and your integrity.

When you release the wrong clients, you create space for the right ones. Clients who trust you, collaborate with you, and make the work not just profitable but meaningful.

So, if you ever find yourself stuck with a client who leaves you drained and frustrated, remember this: some money just isn’t worth the cost.

And sometimes the most professional thing you can say is simply, “Thank you, but I don’t think we’re a good fit.”
