How do you handle different opinions from yours and disagreements in general?

This seems like you're asking a question about basic social skills, and it's only tangentially related to development. I'm not saying that to dunk on you, but it seems like maybe you're framing the entire issue incorrectly?

that's not my point. tp says "just accept the mess and go on with your life, but do your best". I'm saying this is an oxymoron.

I think you may be proving the point I was attempting to make ;)

You do your best within the constraints you're given, which is what is being said in your example. You are welcome to make your arguments for or against a decision (as far as office politics allow), but just as there is a breaking point for you being told to do something you feel is "incorrect," there is a breaking point where you become "the guy who always gives them a hard time."

Soft skills are important as technical when you're working with others. You have to pick and choose your battles. Don't confuse a platitude with a literal decree. Does that make more sense?
