Little known AI prompting tricks that actually make a difference

Not talking about the obvious stuff like be specific or give it context most people know that already. I mean the smaller things that actually change the quality of the output noticeably. For me the biggest one was telling the AI what role to play before asking the question. Something like pretend you are a senior marketing manager with 10 years experience and then asking your question. The difference in output quality is actually significant. Another one I found useful is asking it to give you multiple versions of the same thing rather than just one. That way you can pick the best parts from each version and combine them. What are yours? The more specific and practical the better. Would love to build a proper list of things that actually work rather than the generic advice you see everywhere.
