I think the words are right. My problem with it is that I associate it with people who use it as an excuse to give up. They focus on the idea that they can't change much of anything, so have to accept it. If I were to change it, I would treat the idea that I can't change something as a claim requiring positive proof and being subject to regular challenge. (I'd also filter it for things about which I care and things about which I don't care. But that's kind of beside the point.)
