Your Experience Is a Depreciating Asset

Here is a truth most professionals do not want to hear: your experience is depreciating. Not your judgment. Not your stories. Not the hard-won wisdom of navigating difficult decisions under pressure. Those retain value and even appreciate over time. But the specific tools, techniques, certifications, and domain expertise you rely on every day? Those are losing value from the moment you acquire them.

Think of it like buying a car. Nobody buys a car as an investment. It is a depreciating asset—a tool to get you from A to B, and maybe a prestige tool to feel good about. But it will depreciate, and at some point you will need a new one. Experience works the same way. The moment you gain it, it is already depreciating.

This is not cynicism. It is economics. Research published in the American Economic Review found a measurable skill depreciation rate of approximately 4.3 percent per year when skills go unused. The World Economic Forum’s Future of Jobs Report notes that half of all employees globally need reskilling as the half-life of technical skills continues to shrink. The data is clear: standing still is falling behind.

The Sunk Cost Trap

The reason most professionals struggle with this reality is psychological, not intellectual. You invested years earning a certification. You spent a decade mastering a methodology. Admitting that the asset is depreciating feels like admitting the investment was wasted. But that is a textbook sunk cost fallacy—the economic error of continuing to invest in something because of what you have already spent, rather than what it is worth going forward.

I see this constantly in my career coaching work. Professionals over fifty often do not make changes until they get punched in the face—and that punch is a layoff. It is painful, stressful, and entirely preventable. They could have been preparing. They could have been assessing which parts of their expertise were still essential and which had become deadweight.

And let us be honest about certifications specifically. You get the PMP. You think it is the end-all, know-all. You get the CBAP. Same feeling. Then something pivots. Now somebody else is making significantly more money with a different credential, and you are clinging to yours because of how much you already invested. That is not strategy. That is sunk cost fallacy dressed up as professional identity.

Preparing does not mean you can prevent a layoff. There is no magic there. Even indispensable techniques fly by the wayside when someone is making large-scale cost cuts and you become a number on a spreadsheet. But preparing means you are ready. You have your career plan, your contacts, your references, and you have already been doing skills redevelopment. When it happens, you hit the ground running instead of scrambling.

What Does Not Depreciate

The good news is that not everything loses value. Your stories, your decision-making patterns, your ability to read a room and navigate ambiguity—these are durable assets. Sound decision-making is not magic. There are techniques, and people should use them consistently. Decision-making will not depreciate in value until AI takes over all our decisions for us, and that is a conversation for another day.

What depreciates is the tooling. The specific systems. The narrow expertise that was cutting-edge five years ago and is now table stakes or obsolete. The certification that once differentiated you but is now so common it barely registers on a resume.

The Unlearning Imperative

Barry O’Reilly puts it simply: what has made you successful in the past does not promise to continue to bring you success in the future. The metaphor he uses is a water bottle being overfilled. New information cannot enter until old information is released. But that old information is not just data—it is tied to underlying beliefs about what makes you competent, what makes you valuable, what constitutes professional identity.

Breaking those beliefs is the beginning of the unlearning process. And the only way to do it is to go into it like you do not know anything.

This is especially acute in the AI era. Every knowledge worker is being asked to integrate AI into their workflow, but the use cases are wildly individual. You cannot sit in a lecture and learn your AI workflow. You have to practice, experiment, fail, and iterate. That requires letting go of the belief that your current way of working is optimal—because it almost certainly is not anymore.

So here is the question: which parts of your expertise are still appreciating, and which have become a noose you could hang yourself by? If you cannot answer that clearly, you are overdue for an honest audit. And if you are waiting for a layoff to force the question, you are already behind.

The moment you get experience, it’s already depreciating. You’ve got to live the rest of your career in a process of unlearning—assessing what is most essential in what you know and dropping what’s getting useless so you can spend more time digging into something else.
