Have you ever had the experience of going into a piece of code to make a seemingly simple change and then realizing that you\'ve just stepped into a wasteland tha

    You're absolutely right that there's a right time and a wrong time to rewrite (and destabilize) the code.

    Reminds me of an engineer I knew who had a habit of diving in and doing major rewriting whenever he felt like it. This drove the QA staff for his product up the wall -- if he report a bug about something trivial, the bug would get fixed, but the engineer's major rewrite of stuff he noticed while fixing the one bug would introduce fifty other new bugs, which then the QA staff needed to track down.

    So one way to cure yourself of the temptation to do rewrites is to walk a mile in the shoes of the QA engineer who has to test, diagnose, and report all those new bugs. Maybe even lend yourself to the QA department for a few months to get a personal feel for the type of work they do (if you've never done that).

    Another suggestion would be to make a rule for yourself to write up notes to describe any change. Perhaps post these notes when you check in code changes to source code control. You may be motivated to make the changes as minor as possible this way.
