Making It Cheap to Change Your Mind

September 01, 2026

The tax bill turned up months after I'd signed on the dotted line.

Large, unpaid, and nowhere in the books of the business I had just bought into. Not buried in them, absent from them. By the time I found it I'd handed over more than half my required capital contribution‚ money I understood almost immediately I'd never see again. The company was barely cash flow positive. My new partners were broke.

I'd gone into this properly, or I thought I had. I knew the books of a small operating business weren't my area of expertise, so I hired a business valuation expert to run due diligence alongside me. He asked for the business tax filings, which is exactly what I would have asked for. We got them‚ real returns, filed on time, several years of them.

The CFO had filed every one of those returns and paid none of them.

One thing we never asked for: cancelled checks. We accepted the filings as evidence, and a filing is evidence of precisely one thing, that somebody filed. It says nothing at all about whether anybody paid. We also never asked the partners for personal financial statements, which‚ had they answered honestly‚ would have shown me the thing that actually mattered. I paid a professional to value a business. It never occurred to me to value the men.

My attorney, meanwhile, was worth every dollar. He'd written an out clause into the partnership agreement, and what I'd just found triggered it cleanly. This was precisely what the clause was for.

So, a documented act of concealment, a lawyer-built exit, and a professional's confirmation that I hadn't been careless. Every reason to leave, and permission from every direction.

I stayed.

The money wasn't the reason, though it made a convincing costume

Let me deal with the capital first, because that's where people assume the story explains itself. Of course he stayed‚ he had money in it.

The money was gone either way. That isn't hindsight; I knew it at the time. Leaving wouldn't have recovered a dollar, and staying could only add to the pile. In the only sense that matters, the exit was free.

So what was I protecting?

I could have told you it was the money. I'd have said something about giving it a chance to come back, and it would have sounded like prudence. It wasn't prudence. Leaving meant announcing‚ weeks after telling everyone I knew that I was walking away from a finance career to do this‚ that it had already gone wrong. It meant sitting across from people and admitting I'd been taken. I had spent fifteen years reading prospectuses and inspecting mortgage pools, hunting for the line that didn't add up. That was the job. That was, if I'm honest, my identity. And here I was. Had.

There's an old accounting line I've reached for more than once, “you can't audit for fraud.” It's true as far as it goes. You can audit for error, for sloppiness, for wishful thinking. You cannot audit for people who have decided to lie to you and have arranged the paperwork accordingly.

It's also a little too comfortable, and I'd rather not hide behind it. The honest version is that I asked for the document proving an obligation existed and never asked for the one proving it had been met. That gap is mine. A hungrier process finds it.

But here's what I want to focus on, because it's the point of everything that follows: it doesn't matter.

Whether I should have asked for cancelled checks is a question about the past. Whether to stay in business with broke men who had just lied to me is a question about the future. The two have nothing to do with each other. I let the answer to the first one decide the answer to the second, and that is the most expensive thing I have ever done.

That wasn't my only off-ramp

The week I was due to sign the partnership docs, I got a job offer.

I should be careful how I describe it, because the temptation is to make it shine. It didn't. The offer came from a financial startup that didn't have much money either. The salary was small. There was talk of a bonus, naturally, but nothing guaranteed‚ and I'd spent the previous fifteen years watching my pay climb every year with guaranteed bonuses stacked on top of it. This was nothing like that.

What it was, though, was a chance to work again with people from my old firm, doing work I was good at. My gut said take it. I mean that literally‚ I remember the feeling, I can, “see,” myself walking around the back yard with the offer letter, and I remember my gut saying, “cancel the other thing.”

I told myself I declined out of obligation. The partners had made plans around me; backing out would have left them somewhere difficult. And I did feel that, honestly.

But underneath it was something a good deal less flattering. The number was too small and I was too proud. All that rising guaranteed compensation had quietly taught me I was a person who got paid a certain way, and taking a startup salary meant being somebody else for a while. I wasn't willing. That's not prudence and it isn't loyalty. That's ego‚ hubris, if I'm being accurate‚ a leftover artifact of Wall Street that I carried out the door with me and never thought to examine.

So I honored a commitment to a group of men who were, at that very moment, sitting on a tax bill they had decided not to tell me about.

There was also my dad.

He told me not to do the business. He wasn't dramatic about it, that wasn’t his style. He wasn't unkind, he believed in me. He just didn't think I should start a business. He'd watched his own mother run the family grocery store and butcher shop, and he knew what that life actually took: the hours, the thinness of the margins, the way it eats the family along with the owner. He was trying to hand me that experience, secondhand, for free.

Me? I was forty years old. I had a Wall Street career behind me and a spreadsheet in front of me, and I was certain‚ and I do mean certain‚ that I could, do it better.

I could not do it better.

The thing that actually goes wrong

Fifteen years on, I run a financial planning practice, and I spend a meaningful part of every week giving people advice they don't take. Every advisor does. It's the quiet, unglamorous frustration at the center of this work, and the industry's standard explanation is that clients are irrational, or undisciplined, or don't understand the math.

I don't believe that anymore, and my own file is why.

Let’s look at my three potential exits again. Not one of them failed on information. At every decision point I had what I needed‚ my father's experience, my own gut, and finally a documented deception plus a signed legal mechanism for acting on it. The advice was there. Advice was never the missing ingredient.

What stopped me the first time was certainty. The second time, pride wearing obligation's clothes. The third time, shame‚ a verdict on my past masquerading as a decision about my future.

Those last two aren't finance problems. They're psychological problems wearing a finance costume, and I'd argue most of what the industry writes off as client irrationality is exactly the same thing. The man who won't trim the concentrated position isn't confused about diversification; he told his brother-in-law it was going to a hundred. The woman still funding the failing side business past every rational stopping point isn't bad at math; she announced it at Thanksgiving. The couple bleeding on a rental property know precisely what it's costing them every month. What they don't know is how to explain the reversal to the version of themselves that bought it.

People rarely fail for lack of a warning. They fail because reversing a public commitment costs more emotionally than continuing into a financial disaster.

Those are prices we are all terrible at setting. I had a career's worth of training in valuing obligations, and I still got it wrong by an order of magnitude‚ because I put my embarrassment on one side of the scale and years of my family's financial life on the other, and somehow the embarrassment won.

What I try to do about it

I have to be careful here, because there's an obvious wrong lesson sitting right in front of me.

The wrong lesson is: my father was right, therefore warn everybody.

He happened to be right. But his reasoning wasn't necessarily as directly applicable as he believed. It was one grocery store, in a different era, in a different industry, and plenty of people get that same warning and go on to build something good. Advice that turns out right is not the same thing as advice that was well reasoned. If I let, "he was right," curdle into, "always caution," I'll spend the next fifteen years talking clients out of things that might have been the best decision for them. Nobody needs another advisor whose entire contribution is a frown.

The better answer is this: if the binding constraint is the cost of reversing course, then that cost is the thing to engineer early, while it's still cheap.

This means the conversation isn't focused on, “don't,” it's, focused on, “let's do this, but before we start, let's agree on what we're watching for and what we do if we see it.”

So I try to name the, “tax bill,” in advance. Not a specific one‚ its equivalent, or whatever it happens to be for the decision in front of you. If something material was hidden from you, we're out, and being out isn't failure, it's the plan working exactly as designed. We write it down while everyone's calm, before anybody's ego has welded itself to the outcome. We say it in front of your spouse, so there's a witness. We decide in advance that changing course on new information is the smart thing you agreed to do, rather than the humiliating thing you got forced into.

I also try to look hard at the people, not just the numbers. I paid an expert to value a business and never thought to ask the first hard question about the men I was about to be legally tied to. The industry makes that same trade constantly: model a portfolio to four decimal places, but never ask what your loud Harvard grad brother-in-law thinks of the plan, or whether your marriage can survive the budget just built for it.

That's not pessimism. It's a stop-loss. It may be the most encouraging thing anybody can hand you: advance permission to change your mind later without it meaning you were an idiot earlier.

I never got that. I don't think my father knew to offer it, and either way I'm fairly sure I wouldn't have accepted it at forty. But it's the only version of his advice that stood any chance of reaching me‚ because receiving it wouldn't have required me to concede a thing.

Why "I told you so" is worse than rude

Everyone knows not to say it. It's unkind, it's useless, the damage is done.

It's worse than that, and it took me a long time to see why.

Every time an advisor cashes in on having been right, he teaches the person across the table‚ and everyone else watching‚ that admitting an error in front of him is emotionally expensive. This is precisely the belief that kept me in that business years longer than I should have stayed. Being right out loud raises the price of the next reversal. In that moment the advisor is quietly making it harder for his client to do the one thing he most needs them to be able to do.

So the discipline isn't just biting my tongue after the fact, it's making reversal cheap, every time, on purpose. "New information, new decision," has to be something you've heard me say when it was easy, or you won't believe me when it's hard.

The part I have to watch in myself

I'll be honest about one more thing, since I've been honest about the rest.

That financial startup did more than fine. The people who took the jobs‚ my old colleagues, the ones I'd have been sitting beside‚ built an amazing company and had real success.

I've known that for years. I still have a hard time seeing the sign on top of the building when I drive by. And I miss managing bond funds besides; I was good at it, I liked it, and there's a version of my life where I never left. I've replayed those three exits more times than is healthy, and there is an ongoing risk that this entire line of thinking curdles into something bitter‚ that I become the guy who tells you about the road not taken until you stop asking him about anything at all.

Here's what keeps me honest about it. Running that arithmetic is the same mistake I already made. What those men earned is a fact about a path I didn't take. What I do with the next fifteen years of my own life is a question about the future. Letting the first one set the temperature of the second is precisely the move that cost me financial independence, and I've paid too much for that lesson to keep buying it again.

I don't want to be the bitter guy, and I don't think I have to be‚ because that experience is the only thing that gives this conversation any weight at all. Anybody can tell you to be disciplined. What I can say is narrower and a good deal more useful:

I know what it costs to admit in public that you were wrong. I paid late instead of early, and I can tell you with some authority that late is always more expensive.

You don't get that from a designation. You get it the way I got it.

So: warn you, or catch you?

That was my question starting out, and I've come to think it's a false choice.

The work before the decision and the work after the failure turn out to be the same work. What makes me useful to someone standing in the wreckage of a thing they were warned about is exactly what would have made me useful beforehand‚ being the one person in their life whose regard for them doesn't change with the outcome.

That's the whole thing. If my good opinion of you depended on your decisions working out, I wouldn't be a safe person to bring bad news to, and I'd be the last one you called. It doesn't, so I can be the call you make while the call can still do some good.

My father wasn't wrong. He was early, and he was talking to someone who had already made changing his mind too expensive to afford.

I'd like to be cheaper than that.
