How to Escape the Sunk Cost Trap in Your Career
"At fifteen, I had my mind bent on learning. At thirty, I stood firm. At forty, I had no doubts."
I am thirty now.
When I look back at my life before thirty, it was not always smooth sailing. Some interviewers even pointed out that my experiences had significant ups and downs. I took those comments as a compliment because through the storms, there were growth and innovation.
Allow me to talk it through:
Although my mind was bent, twisted, and smashed, I was quite normal before the age of 16. It all started that year when I picked up a brush and a pencil and learned how to paint. I became an art student. In college I majored in industrial design. After graduation, the world seemed like a puzzle to me. I wanted to understand why those designs needed to be made and who should make decisions. So I went to the U.K. and studied Creative and Cultural Industries Management. Then I joined a startup and an FMCG company as a marketer in China.
Now, here I am, typing this post for the blog I built in Auckland, New Zealand, after finishing an MBA at the University of Otago.
Some people would call this a distraction or inconsistency. I prefer another phrase: connect the dots and make things right.
But here is where it gets interesting.
The longer we walk down one road, the more expensive it feels to turn around. Not because the new road is worse. Not because the old road is still right. It feels expensive because we have already paid.
Let me introduce the sunk cost fallacy.
In economics, a sunk cost is money, time, effort, or energy that has already been spent and cannot be recovered. The rational rule is simple: ignore sunk costs when making the next decision. Ask what the future value is, not what the past has cost.
Simple. Almost annoyingly simple.
But our lives are not spreadsheets. We do not look at a job, a degree, a business, a relationship, or a city and calmly say, "Past investment is irrelevant." We say something much more human:
"But I have already spent five years here."
"But I studied this subject."
"But people know me as this kind of person."
"But if I leave now, what was it all for?"
These are common sunk cost fallacy examples. A founder keeps funding a product because the first version took two years. A manager stays in a role because the title took a decade to earn. A student finishes a degree they no longer want because dropping it would feel embarrassing. A person keeps reading a book they dislike because they are already halfway through it.
Wait a minute. Does this mean we should quit everything once it becomes difficult?
Of course not.
Perseverance is not the enemy. Commitment is not the enemy. Long-term thinking is not the enemy. The danger is when we confuse loyalty to a past decision with responsibility for a better future. Sometimes staying is wisdom. Sometimes staying is fear wearing a wise-looking mask.
This is why the sunk cost trap is especially powerful in careers. Work is not just work. It becomes identity. If I leave design, was I wrong to study it? If I leave marketing, did those years mean nothing? If I start again, will people think I failed?
But hold on. Maybe the old path was not wasted. Maybe it was training.
My art background did not disappear when I moved into business. It changed the way I saw brands, systems, and people. My design education did not vanish when I studied management. It gave me a way to think visually about strategy. My marketing work did not become useless when I built ClearMind. It helped me understand how people tell stories to themselves before they make decisions.
Our previous experiences are not always anchors. Sometimes they are compost.
The question is whether the next investment still deserves the next piece of your life.
That is the heart of Sunk Cost Release. It does not ask you to disrespect the past. It asks you to stop letting the past vote on a decision it can no longer change. If the question is more immediate, use a should I quit my job decision framework to separate burnout, fear, direction, and sunk cost before you act. If the question is whether a whole career chapter needs to change, use a career change at 40 decision framework to inspect the next decade more clearly.
When I face this kind of decision, I find three questions useful:
- If I had not already invested anything, would I choose this again today?
- What am I afraid people will think if I stop?
- What future cost am I accepting just to make the past feel justified?
The third question is the sharp one. It turns the problem around. A sunk cost is already gone, but continuing creates a new cost. One more year in the wrong role. One more round of funding into the wrong product. One more commitment made only because leaving would hurt the story.
This is also why hindsight bias is dangerous. Once the outcome appears, we rewrite the past and tell ourselves the signs were obvious. A decision journal helps because it records what you knew at the time, before memory starts cleaning up the messy truth.
If you are stuck between staying and leaving, a premortem can also help. Imagine you stay for another year and regret it. What happened? What warning did you ignore? Then imagine you leave and regret it. What did you underestimate? The goal is not to scare yourself. The goal is to see both futures honestly.
Lao Tzu wrote, "A journey of a thousand miles begins with a single step." I used to read that as encouragement to start. Now I also read it as permission to redirect.
The path you have walked matters. It shaped you. It taught you. It gave you texture.
But it does not own you.
