Right.  I learned this lesson the hard way (learned it more than once,
in fact).  Now I just plan for it and things go so much better.
Software is not infinitely malleable, and at some point you end up
inserting new errors for every error you are removing, or every
feature you are adding or changing.  And then, depending on your
company culture (or your personal standards), you either throw it away
or ship it.
