Always Be Changing Existing Code

Why change perfectly servicable code today when there are problems to solve?

“I’d be changing it again next week. So where’s the value? Might as well keep it as-is.”

When you are inclined to change code without defects, this could indicate a new understanding that needs expressing.

Changing existing code to reflect a new understanding is all we have. This is how we pay off debt in our design.

Do not suppress that impulse.

The backlog of things to do never ends anyway.
