This sounds like a dangerous mindset. "I don't ever want to even hear about it if what I'm doing is ridiculous". I am not attacking you or saying that what you're doing is wrong, I'm just curious/cautious about the motives behind not wanting to know if there are better/more productive ways of doing things that you just might not know about? Collaboration is usually a very good thing, in spite of the small % of terrible teammates you occasionally get.
