Walking away expensively can still be far less expensive than staying in foolishly. Not every loss is a bad loss.

One of the hardest things in dealmaking is recognizing that money already spent should not be allowed to make the next decision for you. That sounds obvious in theory. It feels much less obvious when the numbers are real.

I was once in a transaction that cost me roughly six figures in legal fees, diligence costs, and related expenses before I finally walked. That hurt. But it would have hurt far more to close a deal that no longer deserved confidence.

That is the part many people miss.

By the time a deal becomes seriously unstable, buyers often feel trapped by what they have already invested. Money. Time. Reputation. Emotion. Narrative. Momentum.

And all of it starts whispering the same thing: “Do not let this go to waste.” That is exactly when discipline becomes expensive. And necessary.

A sunk cost feels painful because it is visible. A bad closing can be much worse because it continues.

One of the most important acquisition lessons I have learned is this: Not every loss is a bad loss. Some losses are tuition. Some are escape.

And some are the price of refusing to turn a problem into a future obligation.
