How do I write good AI prompts if I've never done it before?

Start by telling the AI exactly what role to play, what output you want, and what to avoid — that simple three-part structure will get you 80% of the way to great results even if you've never written a prompt before. Most beginners overcomplicate this. They write vague one-liners like 'write a blog about coffee' and then wonder why the output is generic. A better prompt looks like this: 'You are a friendly barista writing for home coffee beginners. Write a 500-word guide on choosing your first espresso machine. Cover budget, ease of use, and maintenance. Avoid technical jargon and don't mention specific brands.' See the difference? You've given the AI a persona, a clear task, specific angles to cover, and guardrails. I've found that the 'what to avoid' part is the secret weapon nobody talks about. Telling the AI what you don't want is often more powerful than telling it what you do want. One more tip: if the output isn't quite right, don't start over — just say 'make it more casual' or 'shorten the paragraphs.' Iterating is faster than perfecting the first prompt.
