Start a money-saving challenge you'll actually finish

Vague 'spend less' never sticks. Get a short challenge with clear rules, a tracker and a prize that isn't more shopping.

Updated 17 Oct 2026

The prompt · ChatGPT

Help me design a money-saving challenge.

How long: [e.g. 7 days, 30 days]
What I'm saving for or avoiding: [goal]
What I must still spend: [rent, food, travel to work]
What usually makes me quit: [e.g. social plans, kids' activities]
Reward if I finish: [something that isn't more shopping]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Clear rules in five lines or fewer.
2. A simple tracker I can tick each day or week.
3. Two 'escape hatches' for real life so one bad day doesn't end it.
4. A message I can send a friend who's doing it with me.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, figures or products. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.

A short example

Fill the blanks, then paste. e.g. 7 days, 30 days: a short note you already have. goal: a short note you already have. Leave the rest of the prompt as written.

This does not give tax advice. The books stay in the accounting system.
