Why Practice Without Feedback Is Just Rehearsing Your Mistakes
When I left medical school, I decided to get a piano performance master’s degree. I’d played since childhood, knew the theory. I thought it would be manageable.
It wasn’t.
Private lessons where professors stopped you mid-phrase to correct exactly what your left hand was doing. Master classes in front of peers. Eight hours of practice a day. A one-hour graduation recital — 220 pages memorized, unfamiliar piano, unfamiliar stage, no margin for error.
Feedback wasn’t an add-on to the process. It was the process.
A few years later I became an SE and assumed call recording tools would give me the equivalent.
They didn’t. Not because the tools were broken — because the loop was.
Every team I’ve been part of had recordings. Scorecards. Conversation intelligence dashboards. The infrastructure for feedback was there. What wasn’t there: any evidence that practitioners saw it, processed it, or changed anything because of it.
Calls would happen. Scores would generate. The next call would start — same opening question, same objection fumbled the same way.
The recordings existed. The scorecards ran. Nobody closed the loop.
Ericsson spent 30 years studying expert performance. His finding: it’s not practice that builds mastery. It’s deliberate practice — immediate specific feedback on each attempt, targeting the exact sub-skill you haven’t yet built. Without it, you don’t improve. You just reinforce whatever you’re already doing, including the mistakes.
A rep can do 200 discovery calls and never improve their opening question. Not because they didn’t try. Because no one ever told them specifically what was wrong — and what to try instead.
The tool recorded it. The scorecard flagged it. Nobody closed the loop.
The fix isn’t a better tool. It’s treating the feedback loop as the program itself.
Feedback specific enough to act on. Practice on the flagged sub-skill before the next live call. Managers who protect time for this before the week starts, not after deals close.
Eight hours a day and a professor in the room made me a better pianist than I ever expected. The same discipline turns a call library into a coaching culture. Without it, you’re just recording your mistakes at scale.
What does your feedback culture actually look like — the real one, not the one in the QBR deck?
