I don't do UI code but backend systems. Basically ETL and Middleware adapters and the like. I have the tendency to want to keep working the code to make it better. I have however found that my code usually works well long before the I get to the stop fiddling point. I don't work in a team that supports my code, it is just myself. So it is all about my own meter to gauge when to stop tweaking.
