A while back I wrote about the idea of zero-based thinking, a concept I first heard from Brad and Katie Donegan. The basic question is simple:
Knowing what you know today, would you make the same decision again?
At the time, I used examples like trading in a car or deciding whether our house still fit our lifestyle. After another year of slow travel and a lot of reflection, I think I’ve come to appreciate the idea even more. One of the biggest mistakes we make is assuming that because something was the right decision five, ten, or twenty years ago, it must still be the right decision today. It doesn’t. In fact, I would argue that it usually isn’t…
There Isn’t One Right Answer
I think one reason people struggle with big decisions is the fear of making the wrong one. We spend months or years trying to optimize every variable because we imagine there is a single perfect choice hidden somewhere. I don;t think that’s true. Life is not a multiple choice test and most of the time there are multiple correct answers 🙂
You could live in Texas or Nebraska and be equally happy. You could retire at fifty-two or sixty-two and still have a wonderful life. You could buy the house or rent the apartment and make either one work. Realizing that has helped us avoid analysis paralysis. Instead of obsessing over “What if we choose wrong?” we try to ask, “Is this a reasonable choice based on what we know today?”
Then, once we’ve answered yes, we move forward. After all…
Decisions Don’t Have to Be Forever
The other part of zero-based thinking is remembering that very few decisions are irreversible. Commit to making the best choice you can with the information available at the time, but don’t be afraid to revisit that decision when circumstances change.
In fact, I think periodically questioning your assumptions is healthy.
Take my university job, for example. I absolutely loved teaching there. The students were fantastic, the work was meaningful, and I could easily have imagined staying for many more years.
Then COVID happened. After the pandemic, the university made the decision to shift to 100 percent online instruction. I’m perfectly capable of teaching online, but I don’t enjoy it nearly as much as being face to face with students, and I don’t think it creates the same impact.
So I re-evaluated. The job hadn’t become bad. It had simply become a poorer fit for the person I had become and the life I wanted to live. Moving on wasn’t admitting I had made a mistake. It was recognizing that circumstances had changed.
The Same Principle Applies Everywhere
I’ve seen the same pattern play out over and over again.
Our house was exactly what we needed when we had young kids and jobs in the local schools. Four bedrooms, a converted playroom, proximity to the elementary school and junior high, and a neighborhood pool across the street all made perfect sense.
Today? Katie and I don’t need most of those things anymore.
The minivan we bought to haul kids and road trip around the country was a great vehicle for that season of life. I mean, it had DVD screens that flipped down from the ceiling! Now, though, we would rarely use the second row seating, much less the third. And the DVD player? Sigh…
Even our current experiment with slow travel reflects this mindset. If we eventually discover that one location fits us perfectly, we can stay. If we decide after a few years of slomaidc travel that we miss having a permanent home base, we can buy another house.
Nothing says today’s decision has to lock us in forever.
The Financial Lesson
I think this idea has huge implications for financial independence. Too often we cling to investments, careers, houses, or possessions because of sheer inertia or because we’ve already invested so much time or money into them. Economists call this the sunk cost fallacy.
Zero-based thinking asks different questions.
- If I didn’t already own this house, would I buy it today?
- If I weren’t already working this job, would I accept it today?
- If I didn’t already have this investment, would I purchase it today?
- Even bigger… If I could live anywhere in the world, would I still choose to live in this community, state, country, etc.
Sometimes the answer is yes, but sometimes it isn’t. Neither answer is wrong.
The Takeaway
For me, zero-based thinking has become less about making perfect decisions and more about giving myself permission to evolve. Life changes. We change. The information available to us changes.
There is no prize for stubbornly sticking with yesterday’s best decision after it has stopped serving today’s goals. Make the best choice you can with the information you have. Then, every once in a while, have the courage to ask the question again.
You might discover that the right answer has changed. And that’s more than okay. That is growth…
