Most of the adults I work with run into two quiet, nagging problems over and over: big purchases that feel like a gamble, and awkward emails where you have to say “no” without burning a bridge. This week we’re going to use AI for both: **researching a major purchase decision** and **writing a professional decline email**. These are small moments that add up to stress, second-guessing, and lost time. You deserve better tools.

Try at least one before Sunday. That is the whole assignment.

Use Case 1 of 2

Use Case 1: Researching a major purchase decision

On Tuesday night at 9:15 pm, Linda is sitting at her dining room table with her laptop open and three tabs fighting for her attention: one for a $2,800 adjustable bed, one for a cheaper $1,400 option, and one for a “Top 10” review article that looks suspiciously like it was written by the bed company’s marketing team. She’s 61, her back has been bothering her for years, and her doctor finally said, “It might be time to invest in a better mattress.”

The problem is not that Linda can’t find information. She’s drowning in it - manufacturer claims, influencer reviews, five-star ratings with no substance, and a few angry one-star reviews that make her want to give up altogether. She doesn’t want to spend hours reading spec sheets, but she also doesn’t want to spend thousands of dollars and regret it for the next decade. What she really wants is a clear comparison: what matters for someone with back pain, what’s marketing fluff, and where the trade-offs are between these two models. That’s the kind of thinking AI can help with - if you give it the right instructions.

Here is the exact prompt to use:

Copy and paste this into ChatGPT or Claude:

I am a 61-year-old woman with chronic lower back pain, shopping for an adjustable bed and mattress. I am deciding between these two options:

Option A: [paste product name, brand, price, and the main features/specs from the product page] Option B: [paste product name, brand, price, and the main features/specs from the product page]

1. Based on what is publicly known about these products and typical needs for someone with back pain, give me a clear comparison in plain English: comfort, durability, warranty, ease of use, and total cost over 10 years. 2. Explain what matters most for back pain (in simple terms) and which of these features are probably marketing buzzwords versus genuinely useful. 3. Create a short list of 5 - 7 questions I should ask the salesperson or customer support before I decide. 4. Tell me, in one paragraph, what kind of person should choose Option A and what kind of person should choose Option B, without trying to push me either way.

Use headings and short paragraphs. Avoid technical jargon unless you also explain it.

Why this prompt works:

This prompt works because you give the AI context about **who you are**, **what you’re deciding between**, and **how you want the information organized**. You’re not just saying “Which bed is best?” - you’re asking it to compare specific options against your specific situation. You also tell it to translate technical details into plain English and to separate marketing claims from practical concerns, which forces the system to focus on usefulness instead of hype.

AI does not have secret access to internal company data or live inventory; it’s working with publicly available information and its training data, which may be incomplete or out of date. Double-check any exact numbers it gives you (warranty length, prices, return policies) on the actual product websites before you decide. And remember: AI can help you think more clearly, but it should not be the only voice in the room - talk to your doctor, and if the purchase is big, consider calling the company and asking those questions yourself.

Use Case 2: Writing a professional decline email

On Wednesday at 7:40 am, Mark is nursing his first cup of coffee before an 8:30 Zoom call. He’s 54, runs a small consulting practice, and yesterday an old colleague emailed with what sounded like a flattering opportunity: “We’d love for you to join our advisory board. It’s not a paid role, but we think your expertise would be invaluable.”

The truth is, Mark is already stretched thin. He’s trying to grow his business and carve out a little time for himself. He knows if he says yes, it will mean evening meetings, prep work, and emotional energy he doesn’t really have. But he also doesn’t want to sound ungrateful or slam the door on future paid work with this group. He’s been staring at a blank email draft for ten minutes, worrying that whatever he writes will sound either too blunt or too mushy. This is where AI can help - not by being “fake,” but by giving him a clean starting point and language that balances honesty and professionalism.

Here is the exact prompt to use:

Copy and paste this into ChatGPT or Claude:

You are helping me write a short, professional email where I decline an unpaid advisory board invitation but preserve a good relationship and leave the door open for future paid work.

Here is the situation, in my own words: - I’m a 54-year-old independent consultant with limited bandwidth. - An old colleague invited me to join an unpaid advisory board for their organization. - I appreciate the invitation and respect their work, but I do not have the time to take on an unpaid ongoing commitment. - I would be open to future conversations about paid, well-scoped projects.

Write a concise email (no more than 200 words) that: - Starts with genuine appreciation and a specific positive note about their organization. - Clearly and politely declines, mentioning time and focus constraints without over-explaining. - Leaves the door open for future paid collaboration. - Sounds like a thoughtful professional in his 50s, not a teenager or a corporate robot.

After you write the email, explain in 3 - 4 bullet points why the wording works and where I could customize it to sound more like my own voice.

Why this prompt works:

This prompt works because you tell the AI **who you are**, **what the relationship is**, and **what you want the email to accomplish**, not just “Write a decline email.” You set boundaries on length and tone, and you describe the key emotional balance: appreciation, clarity, and future possibility. Asking for a brief explanation of the wording forces the AI to reveal its reasoning, which makes it easier for you to tweak phrases to sound like yourself.

AI-generated emails can drift into vague, slightly generic language that doesn’t sound like you. Before you send anything, read it out loud and change any phrase you wouldn’t say in conversation. Also, be careful not to let AI talk you into over-apologizing; you are allowed to say no without turning it into a confession. The tool should support your boundaries, not erase them.
