Lesson 2 · Beginner 12 minutes Hands-on

Writing Better Prompts: The 3-Part Formula

Lesson 1 showed you that vague prompts give vague answers. Now let's turn that into a repeatable habit. In 12 minutes you'll learn the three-part formula that makes almost any AI request better — and you'll write one yourself.

By the end, you'll have:

  • A simple formula for any prompt
  • Written a from-scratch prompt using it
  • A reusable template you can keep
  • The "brief" mindset that ties it all together

The Lesson

Follow along with a real AI chat open. Each step builds on the one before.

1

Recall why vague fails

In Lesson 1 you asked the AI to "write an email about a price increase" and got something bland and unusable. That's the baseline. Here's the quick version of why: the AI had no idea who it was writing for, what you wanted to achieve, or how it should sound.

Every prompt is missing information by default. Your job is to fill the gaps before they turn into a bad answer.

The three-part formula

Almost every good prompt answers three questions. Learn them once and you'll use them forever:

WHO

Who is it for? What do they already know? What tone fits?

WHAT

What exactly do you need produced? State the outcome clearly.

HOW

Length, format, style, must-haves. The specifications.

Remember it as: Who it's for, What you want, How it should look. Three answers, one great prompt.
3

Watch it fix a bad prompt

Here's a weak prompt, then the same request rebuilt with all three parts:

Before: Write something about our new product.
Who: busy small-business owners who don't know us yet
What: a product announcement they'll actually read
How: 80 words, plain language, one clear benefit, friendly but not salesy, end with a simple next step

Same request. Completely different result. Nothing clever was added — just the three answers.

Now you write one

Pick a real task you did this week — an email, a summary, a plan, a message. Fill in the template below with your own three answers, then paste it into your AI chat.

Your turn — fill in the blanks:

I need help with [what you want]. It's for [who it's for]. Make it [length, tone, and any must-haves].

5

Refine with one-line follow-ups

First drafts are rarely final. Instead of rewriting your prompt, just reply with a short adjustment — exactly like you would to a colleague handing you a first attempt:

"Make it half as long" "Warmer tone" "Give me 3 versions" "Simplify for a beginner" "Cut the jargon"
Pro habit: the best results come from a quick back-and-forth, not one perfect prompt.
The mindset that makes it click

Why this is just a good brief

WHO, WHAT, HOW isn't an AI trick — it's how you'd brief a brilliant new employee on their first day. You wouldn't say "write something about our product" and expect gold. You'd say who it's for, what you need, and how you want it.

The same holds for people and for AI. Clarity in, quality out. Every prompt is just a brief — and the formula above is the shortest good brief there is.

What the finished prompt looks like

"I need help writing an email about a 10% price increase. It's for my small landscaping customers, who've been with us a year or more. Make it warm and apologetic, under 120 words, and end by offering to talk it through."

One paragraph. Three answers. Noticeably better output — every time.
