To add to your point of treating company's money as your own -- "Tracking Money" will help understand a lot of corporate priorities and explain a lot of decisions. --I-- may want to update something because "it's the right thing to do / makes for cleaner code / etc". But the management probably has a reason (good bad or ugly) for their own priorities. Advice I read mid-way through my career is "understand your manager's goals and reasons", and it was so simple and yet so... shocking to so many of us techies. We always expected manager to understand our recommendations and priorities. Hubris! :)

(in Public Sector, "Tracking Money", interestingly, did not work as well; but "Tracking Personal Status/Blame/Credit" worked well. The two should be equivalent but in my limited experience there's differences)
