I find there is middle ground between "who the fuck cares" and "I got to fight for what is righteous". Do the job best you can. Accept resources, including skilled human beings, are what they are and unless you own the place there is very little you can do about it. Try to do the best work you can with the resources you are given is all I can say. It does give pleasure to at least try to do a good job.
Yes, I am saying you should be cleaning the decks of the Titanic with all the care you can muster but without being obsessive or neurotic about it. Don't do it for the Titanic, don't do it for all the people who are about to die. Just do it for you.
