Get your coupons ready Reader.
I have a theory that choosing the correct checkout line at the grocery store is one of life's great unsolved mysteries. I don't care how much experience you have or how carefully you study the situation. The moment you commit to a line, something will happen to make you question every decision you've ever made.
You know the situation. You survey the registers, count the people, inspect the carts, and make what you believe is an educated decision. You get behind someone with six items while the person in the next line has enough groceries to survive a three-month winter storm. Naturally, their line starts moving faster. Your cashier needs a price check, someone has a coupon from 2017, and the manager has disappeared into whatever mysterious place grocery store managers go when you need them.
Now you have a choice. You could switch lines, but you've already invested five minutes in this one. Besides, you know the moment you move, your original line will suddenly start moving again. So you stay, watching everyone else make progress while you stubbornly defend a decision that stopped making sense several minutes ago. Not because it's the best line anymore, but because it's the line you chose.
...and it got me thinking.
I wonder how often we do the same thing with decisions that matter a whole lot more than getting out of the grocery store before our ice cream melts.
There is a concept in behavioral economics called the sunk cost fallacy. Essentially, it describes our tendency to continue investing in something because of what we've already put into it, even when the current evidence suggests that changing direction might be the better decision. The time, money, or effort we've already spent begins influencing what we do next, even though none of those things can be recovered simply by continuing.
I think the interesting part is how easily we can disguise this behavior as something positive. We call it commitment. We call it perseverance. We tell ourselves that successful people don't quit, that hard work eventually pays off, and that changing direction means we weren't willing to see something through.
And sometimes those things are absolutely true. There are plenty of situations where persistence is exactly what we need. Learning a difficult skill, working through a challenging relationship, or staying committed to a meaningful goal often requires us to push through uncomfortable moments. The problem comes when we stop evaluating whether our effort is actually moving us toward something worthwhile.
I've seen this play out in sports more times than I can count. A coach develops a system, invests countless hours teaching it, and builds an entire season around making it work. When the results aren't there, the natural response is often to double down. More repetitions, more instruction, more emphasis on execution. The assumption becomes that the system is correct and the athletes simply haven't mastered it yet.
Maybe that's true. Or maybe the system isn't the right fit for the athletes standing in front of us.
That can be an uncomfortable possibility to consider, especially when you've spent months building something you genuinely believe in. Changing the approach can feel like admitting the original decision was wrong. It can feel like throwing away all the time and energy you've already invested. But I wonder whether the bigger mistake is continuing to invest in something simply because we're uncomfortable acknowledging that it needs to change.
Athletes experience their own version of this. They commit to a particular role, team, or approach to their development and begin building an identity around it. Sometimes that commitment creates incredible growth. Other times, the situation changes, their interests evolve, or the environment stops supporting the person they're becoming. Yet they continue because they've already put so much into it. Walking away, or even considering a different path, feels like losing everything they've worked for.
Youth sports can make this especially complicated. Families invest enormous amounts of time, money, and emotional energy into an athlete's development. There are years of practices, tournaments, travel, private lessons, and missed weekends. Eventually, the investment itself can become part of the reason to continue, even when the experience no longer resembles what everyone originally hoped it would be.
I don't think that means people should abandon something the moment it becomes difficult. Quite the opposite. I believe there is tremendous value in working through adversity, honoring commitments, and learning that progress doesn't always happen on our preferred schedule. But I also believe we need to be careful about teaching young people that commitment means never reconsidering a decision.
There is a difference between staying because something still matters and staying because leaving would make the previous effort feel wasted.
Maybe that's the distinction we don't talk about enough. Persistence is valuable when we're moving toward something meaningful, even if the progress is slow. Stubbornness can look remarkably similar from the outside, but sometimes it's simply our refusal to admit that the direction no longer makes sense.
And the frustrating thing is that we usually don't recognize the difference while we're standing in the middle of it. We're too close to the decision. We've defended it, explained it, and convinced ourselves that the next little bit of effort will finally make everything worthwhile. The longer we stay, the harder it becomes to imagine doing anything else.
I think that's why the question shouldn't always be whether we're willing to keep going. Sometimes the more important question is whether we would make the same decision today, knowing what we know now.
If we weren't already invested, would we still choose this path?
That question doesn't erase the work we've done. It doesn't make the experience meaningless, and it certainly doesn't mean the original decision was foolish. We make choices with the information we have at the time. Sometimes those choices work out beautifully. Sometimes we learn something along the way that changes what makes sense next.
The experience still belongs to us, even if we decide to take it somewhere different.
Which brings me back to the grocery store.
Imagine standing there, watching the line next to you move steadily forward while your cashier is still trying to figure out why a bag of apples requires managerial approval. You look at the other register, consider switching, and feel that familiar resistance. You've already waited. You've already committed. Surely your turn is coming soon.
Then you notice something. The person behind you has quietly moved to the other line. No dramatic announcement, no apology to the cashier, no explanation about the years they've dedicated to this particular checkout experience. They simply looked at the situation, made a new decision, and moved.
A few minutes later, they're walking out the door.
You're still standing there, wondering whether you should have followed them.
Maybe the lesson isn't that we should always switch lines. Sometimes the one we're in really is the best choice, even when it moves a little slower than we'd like.
But I do wonder how many times we stay somewhere simply because we can't stand the thought of having been wrong about where we started.
And if you happen to see me at the grocery store this week, staring suspiciously at three checkout lines while holding a rapidly melting container of ice cream, you'll know I'm still working on this one.
Thanks for riding along!
