Latest / Work-Life Balance with Fexingo: Boundaries, Time Management, and Avoiding Career Overload / The Sunk Cost of a Career You No Longer Want
Transcript
- Lucas: So Luna, I keep thinking about a conversation I had last week with a product manager who's been at the same company for seven years. She told me she's completely bored, the product she built is being deprioritized, and yet she can't bring herself to leave. And her reason wasn't 'I love the mission' or 'the pay is great.' It was 'I've put seven years into this.' Luna: That's the sunk cost fallacy, right? We stay because we've already invested, not because staying is good for us. Lucas: Exactly. And it's everywhere in careers, not just in that dramatic example. It's the project you keep resourcing because you've already poured two years into it. It's the certification you finish even though you've realized the field doesn't interest you. It's the job title you cling to because you worked so hard to get it. Luna: What's the distinction between sunk cost and opportunity cost? I always get those mixed up. Lucas: Sunk cost is the past investment that's gone, no matter what you do next. Opportunity cost is what you give up by not choosing the alternative. The problem is, our brains are terrible at ignoring the sunk cost, even though it's irrelevant to the forward-looking decision. Richard Thaler, the behavioral economist, built a whole framework around this called mental accounting. Luna: Mental accounting. That's the idea that we treat money differently depending on where it came from or what we've labeled it for, right? Lucas: Yeah. And we do the same with time. We have a mental account for 'this career path' and we feel like we need to justify the deposits we've made. The problem is, the past is unrecoverable. The only question that matters is: what's the best next move from here? Luna: I have a friend who stayed in a job three years too long because he'd already gotten his MBA specifically to move into that industry. He felt like leaving would waste the degree. Lucas: That's such a classic example. And it's painful because the MBA isn't wasted if he leaves. He still has the knowledge, the network, the credential. What's actually wasted is staying in a role that makes him miserable and stalls his growth. Luna: So what does she do? The product manager, I mean. How do you break that mental loop? Lucas: One thing I've found useful is what I call the future regret test. You ask yourself: if I stay in this role for another two years, what's the probability I'll regret not having left sooner? And if the answer is high, that's a signal. Luna: I like that. It flips the frame from justifying the past to anticipating the future. What else? Lucas: Another is a zero-based review of your career. Instead of asking 'what have I invested?', you ask 'if I were starting from scratch today, would I choose this same path?' If the answer is no, you have your answer. Luna: That's brutal but useful. I think a lot of us avoid asking that question because we're afraid of the answer. Lucas: Right. And there's also a practical angle. Sometimes the inertia isn't just psychological; it's logistical. You've built a life around a job—the commute, the insurance, the social circle. But those are also things you can change. Luna: And if you do decide to leave, how do you frame the experience so it doesn't feel wasted? On a resume, I mean. Lucas: You frame it as a story of evolution, not abandonment. You don't say 'I gave up on my product.' You say 'I led a product through its lifecycle and learned when to pivot.' That's a strength, not a weakness. Luna: That's a good reframe. You know, this reminds me of something you've said before about our own show. We've put so much into building this podcast, and sometimes it's tempting to keep doing things just because we've always done them. Lucas: Exactly. And that's why we appreciate listeners who support us. It's not about the sunk cost of all those episodes—it's about the value we can still create together. If you've gotten something out of this show, and you want to help keep it ad-free and independent, you can support us at buy me a coffee dot com slash fexingo. Luna: It's a small way to say 'keep going,' and it genuinely matters. Lucas: And it also helps us ignore our own sunk costs and focus on what's next. Anyway, back to that question of how to make the decision. I want to talk about a specific tool that might help. Luna: What's that? Lucas: It's called a pre-mortem. You imagine it's two years from now and your current path has failed. You write down the reasons why. That often clarifies what you actually fear and what you need to change. Luna: So instead of predicting success, you predict failure. I've heard that used in project management, but applying it to a career decision is interesting. Lucas: Yeah. And it works because it forces you to confront the downside, which we usually avoid. Once you see the risks clearly, you can decide if they're acceptable or if you need to pivot. Luna: That's a good exercise for anyone who's feeling stuck but isn't sure why. Lucas: And there's also the 10-10-10 rule. You ask yourself: how will I feel about this decision in 10 minutes, 10 months, and 10 years? It's a way to distance yourself from the immediate emotional weight of the sunk cost. Luna: I like that. It puts the decision in perspective. In 10 years, you probably won't care about the seven years you spent—you'll care about the 20 years you have left. Lucas: Exactly. And that's the real opportunity cost. Every year you stay is a year you're not building something else. Luna: So what about the product manager? Did she end up leaving? Lucas: She hasn't yet. We talked through the future regret test and the zero-based review. She realized that if she started fresh, she wouldn't choose her current company. That was a big realization. But she's still scared of the unknown. Luna: That's normal. Change is scary, even when it's the right move. Lucas: Right. And I didn't push her. I just gave her the frameworks and told her to sit with them for a week. She's going to get back to me. Luna: I hope she makes the leap. But it also makes me wonder—are there times when the sunk cost is actually a good reason to stay? Lucas: That's a great question. Sometimes the investment you've made gives you leverage you can't easily replicate elsewhere. For example, if you've built deep relationships with clients over a decade, switching companies might set you back. Luna: So it's not about ignoring the past entirely; it's about weighing it correctly. Lucas: Exactly. The past matters only insofar as it affects the future. If your network, skills, or reputation are transferable, then leaving doesn't waste them. If they're company-specific and perishable, that's a different calculation. Luna: That's a nuance I hadn't considered. It's not just about emotion; it's about the actual value of your accrued assets. Lucas: Right. And that's why I like the phrase 'sunk cost vs. investment.' You have to ask: is this past spend still generating returns, or is it just a memory? Luna: That's a good way to put it. So for anyone listening who's stuck in a similar situation, what's your one piece of advice? Lucas: Do the future regret test tonight. Write down the answer. And if the regret score is high, start taking small steps toward change—update your resume, have a conversation with a mentor, explore what else is out there. You don't have to quit tomorrow, but you can start moving. Luna: That feels actionable. And maybe the question to leave listeners with is: what would you start today if your past investment were irrelevant? Lucas: That's a great place to leave it. Thanks, Luna.
