Thank you! Taking that refactoring advice at face value when I still was quite junior led to me writing an immensely over-abstracted framework that bit me in the butt for years afterwards when trying to debug or add a new feature. Wasn't easy to unlearn...

Thank God you did. I hear of seniors who still do this shit with no real sense of style because they just assume that over-abstracting everything is always the correct thing to do. You're learning, not unlearning!
