The one skill that changes everything: context
The difference between a useless answer and a great one is usually one sentence you didn't type.
The lesson
The same request twice: "write a thank-you note" gets generic mush; add who it's for, what happened, and how it should sound, and you get something you'd actually send. The formula — who's involved + what you want + how it should feel — is the whole skill people call prompt engineering. It's just saying what you mean.
The picture to keep
The Context Sandwich: [who's involved] + [what you actually want] + [how it should feel] = the answer you wanted.
Try it — 60 seconds
I need to write [a real message you owe someone]. Here's the situation: [2 sentences]. Write it in my voice: [friendly / direct / formal]. Keep it under [length].
Copy it into ChatGPT, Claude, or Gemini — whichever you already use. Fill in the brackets with your real life.
Watch out
Give AI context about the situation — never confidential details. Account numbers, health records, other people's secrets stay out of the chat box.
