Why experience can sometimes become our greatest obstacle

4.1 Why what worked before can hold us back today

I once gave an internal presentation at a manufacturing company about markets and branding. For more than an hour, I discussed its public communications, ways of reaching customers, and changes I thought could begin immediately. When we turned to implementation, someone suggested it might take a year or two. “Let me do it,” I said. “In six months, you'll see something taking shape.”

A manager who had long been responsible for the work was irritated. “What do you know? I was doing this 20 years ago.” I have remembered the remark ever since, less because of who was right that day than because it contained a legitimate point. Doing similar work 20 years earlier certainly meant having experience. But what, exactly, did that experience establish?

Experience is an advantage

I value experience. Without it, much of what we do would be slow. A new salesperson tends to take a customer's words literally. Over time, we learn which remarks deserve follow-up, which actions matter more than statements, and which warning signs should not be dismissed. Experience gives us a way into a situation without beginning again from nothing.

The risk comes with the advantage. After repeated encounters, a similar situation can produce an immediate “I know this.” Observation gets shorter. The answer arrives before the problem has fully emerged. The greatest risk of experience is not that it leaves us knowing nothing. It is that it makes us feel we already understand too soon.
