Programmers and the rewrite of code that already works

Most work is hard to take back. A sent letter stays sent. Code is often different. A bad change can be rolled back or fixed within the hour.

That should make letting go easy. For many programmers, it does not. The rewrite runs anyway.

That tells you something. If the fear were about the mistake, an easy fix would calm it. So it is about something else.

The Perfectionism Trap is the name for raising the bar each time you reach it. You may know it as the finished task you cannot hand in.

In code, it hides well. Cleaning up working code even has a job name, and teams praise it. So the pattern can pass for good habits.

The tell is that it has no end point. Each pass finds a new thing to fix, in code that worked yesterday.

Behavioral Interception is the practice of catching an automatic pattern as it begins, intercepting its usual response, and practicing a different action until it becomes more natural.

Start with the body signal, the tight chest just before you ask for a review. Feel it and name the pattern.

Then take a different action. Write down what done means before you start. When the work meets it, hand it in.

Put the next cleanup idea in a note for later. If it still matters next week, plan it like any other task.
