How dare I polish and remove kludges from previous releases. ๐
Also, none of those kludges would have even been necessary if the project scope was properly defined from the start and the project manager didn't let the users keep trickling in new requirements without also extending the deadline.
So yeah, how dare I go back and implement something the way it should have been done the first time?
It is if you don't get pay to run, getting anywhere faster doesn't help you at all, and it costs more energy. And you gain nothing from it. That's my point.
