Pro Work Tip 3: You Are Allowed to Change Careers
If you studied for years in a field, then decided it isn’t for you, you are allowed to leave. You are allowed to leave academia. You are allowed to walk away from the PhD, the postdoc, the tenure track, the discipline you gave your twenties to. Nobody revokes your permission to have a different life than the one you planned at 22.
The Sunk Cost Lie
The biggest thing keeping people stuck is a myth: that years spent studying something are “wasted” if you don’t use them forever. This is the sunk cost fallacy wearing a cap and gown. The years are gone either way. The only question left is what you do next, and “keep doing something that isn’t working, to avoid feeling like the past was wasted” is not a good answer to that question.
Nothing about that time was wasted if you learned something. And you did. You learned:
- How to read dense, difficult material and pull out what matters
- How to write clearly under pressure
- How to design a project, run it, and see it through when nobody was checking in on you daily
- How to sit with not knowing something and work the problem anyway
- How to survive critique of your own ideas without falling apart
That is not nothing. That is, in fact, most of what employers actually want, dressed up in a different vocabulary than your field uses.
Academia Is a Place, Not an Identity
It’s easy to let a field become your whole identity, especially after years of a program designed to demand exactly that kind of devotion. But a discipline is a place you’ve been, not a fact about who you are. Leaving physics doesn’t erase the years you spent thinking like a physicist. Leaving academia doesn’t delete the rigor, the curiosity, or the discipline (pun intended) you built there. You take all of it with you. You’re not starting from zero — you’re starting from everything you already know how to do, aimed at a new target.
What “Wasted Time” Actually Means
Wasted time isn’t time spent on the “wrong” subject. Wasted time is time spent staying somewhere out of fear, obligation, or sunk cost, after you already know it isn’t right for you. That’s the actual waste, not the years already behind you, but the years ahead of you that you’d spend unhappy to avoid admitting the first choice didn’t pan out the way you hoped.
You’re allowed to be someone who studied X and does Y. You’re allowed to have loved a field and still leave it. You’re allowed to have poured everything into a degree and decide the next chapter looks different. None of that makes the previous chapter meaningless. It makes you someone who kept learning, which was the whole point of studying in the first place.
Change the career. Leave the lab, the department, the discipline. Whatever you learned, you keep. Whatever you’re becoming, you’re allowed to become it.
