Latest / Career Skills with Fexingo: Hard Skills, Soft Skills, and Future-Proofing Your Career / The Hidden Tax of Skill Hoarding on Your Career
Transcript
- Lucas: So there's this idea that your most valuable skills are your personal assets — you protect them, you don't teach them to anyone else, because if you're the only person who can do something, you're indispensable. Luna: Right — kind of like a trade secret. Keep the recipe locked in your head. Lucas: Exactly. But here's the thing: a lot of research suggests the exact opposite is true. Hoarding your skills actually makes you more vulnerable, not less. There's a Harvard Business School professor, Heidi K. Gardner — she did a study on this back in 2018. She looked at knowledge workers in law firms and consulting firms, and she found that specialists who hoarded their expertise ended up earning roughly 12 percent less over a five-year period compared to those who actively shared their knowledge. Luna: Twelve percent less — that's a big gap. What's driving that? Lucas: A couple of things. First, when you share your skills, you build a reputation as a collaborator and a leader. That leads to more high-visibility projects, better assignments. Second — and this is the part I find really interesting — sharing creates what economists call 'human capital spillovers.' When you teach someone else a skill, you're forced to structure your own thinking, you often discover gaps in your own knowledge, and you end up learning the skill better yourself. Plus, you free up time to learn new things because you're not the bottleneck on every task involving that skill. Luna: So hoarding has a hidden cost — an opportunity cost. You're not just failing to gain the benefits of sharing, you're actively limiting your own growth. Lucas: Right. And it gets worse. There's this trap I think of as the 'skill tax' — the longer you hold on to a single skill exclusively, the more it taxes your ability to develop adjacent skills. If you're the only person who knows how to run your company's database queries, you spend all your time running those queries. You never learn the new analytics platform, you never learn the data visualization tools, you never learn the business logic behind what people are asking for. So your skill set narrows over time instead of broadening. Luna: And then if the company decides to automate those queries, or migrate to a new system, you're suddenly left with no relevant skills. Lucas: Exactly. I saw this happen at a mid-sized SaaS company a few years ago. There was a software engineer — let's call him Mark — who was the only person who understood the legacy billing code. He'd been there for seven years. He never documented it. He never trained anyone else. He'd push back on every attempt to refactor or replace it, saying it was too complex. And when the company decided to move to a new billing platform, they hired an outside team to rebuild it from scratch. They didn't need Mark anymore — they had a fresh system with full documentation. He was laid off. And the irony is, if he'd spent those seven years training others and gradually modernizing his own skills, he'd probably still be there, or at least have a much easier time finding a new job. Luna: That's brutal. And honestly, I think a lot of people fall into that trap because it feels safer in the short term. You have job security because you hold the keys. Lucas: Right, but it's a false sense of security. The company might not fire you tomorrow, but they'll stop investing in you. They see you as a maintenance cost, not a growth asset. And the moment the business needs to change direction, you're the first person they're willing to let go. Luna: So what's the alternative? How do you break the hoarding habit if you're already in that mindset? Lucas: I think the most concrete thing you can do is create what I call a 'skill release schedule.' Pick one technique, one piece of knowledge, or one process that you're good at — and commit to teaching it to someone else within the next month. It could be a formal training session, a written guide, or just pairing up with a junior colleague for an afternoon. The goal is to make sharing a regular practice, not a one-time event. Luna: And the bonus is, when you teach it, you often get new ideas or see it from a different angle. I've definitely had that experience. Lucas: Absolutely. Speaking of that, you know, this show itself is a kind of sharing practice — every episode we're trying to pass along something we've learned. And if you find these conversations useful in your own career, there's a simple way to support the show and help us keep it ad-free. You can head over to buy me a coffee dot com slash fexingo. It's a low-key way to say thanks, and it genuinely helps us keep doing this. Luna: Yeah, and it's completely optional. We just appreciate you listening. Lucas: So back to the skill release schedule — one concrete example I've seen work well is from a friend who's a data analyst. She realized she was the only person who knew how to build a particular dashboard that the whole executive team relied on. So she started a monthly 'dashboard clinic' where she'd walk through how to build it step by step. After three months, two other analysts could build it from scratch. She then took on a new project building a predictive model — something she'd wanted to learn for years. The company saw her as more valuable, and she got a promotion six months later. Luna: So by letting go of that one dashboard, she unlocked a whole new career trajectory. Lucas: Exactly. And I think that's the key insight: your skill isn't actually diminished by sharing it. If anything, it becomes more valuable because it's now embedded in a network of people who can build on it. That network becomes part of your professional capital. Luna: And it makes you more resilient. If you're the only one who knows something, you're a single point of failure. If ten people know it, you're the expert who built that capability. Lucas: Right. And companies notice that. They start seeing you as someone who multiplies the team's effectiveness, not just a utility player. That's the kind of reputation that leads to raises, promotions, and opportunities. Luna: It also changes how you view your own skills — instead of guarding a static asset, you see yourself as someone who can generate new knowledge and spread it. That's a much more growth-oriented identity. Lucas: So let's leave listeners with a practical challenge. Pick one skill you currently hoard — even a small one — and find a way to teach it to someone else this week. It could be a shortcut in Excel, a negotiation tactic, a way to structure a presentation. Just start small. The act of sharing it will shift your mindset more than you expect. Luna: And if you do it, let us know how it goes. We'd love to hear your stories. That's it for this episode of Career Skills with Fexingo. Lucas: Thanks for listening. We'll be back next week with another skill-focused conversation.
