Here is a good habit to develop: whenever you see a rhetorical question, try – silently, to yourself – to give it an unobvious answer. If you find a good one, surprise your interlocutor by answering the question. I remember a Peanuts cartoon from years ago that nicely illustrates the tactic. Charlie Brown had just asked, rhetorically: “Who’s to say what is right and wrong here?” and Lucy responded, in the next panel: “I will.”
