I needed to determine whether those reasons were genuine or mere justifications for my decision to stop there. So I asked myself the crucial question, “Knowing what I know about the real price of this gasoline, if I could go back in time, would I make the same choice again?” Concentrating on the first burst of impression I sensed, the answer was clear and unqualified. I would have driven right past. I wouldn’t even have slowed down. I knew then that without the price advantage, those other reasons would not have brought me there. They hadn’t created the decision; the decision had created them.
We make justifications for decisions that we’ve committed to, to determine if it’s the right decision ask if you could go back in time would you do it differently.
