Plan a no-spend or simple-living month

Help me plan a no-spend month.

Month: [e.g. January]
Essentials I'll still pay: [e.g. rent, bills, food, travel to work]
Where my money usually leaks: [e.g. takeaways, coffee, online shopping, apps]
What I'm saving for: [goal]
Who's doing it with me: [e.g. just me, the family]

Before you start, ask me up to 3 short questions if anything important is missing. Wait for my answers.

Then:
1. Clear rules: what's allowed, what's not, and what to do about birthdays.
2. Ideas to cut the leaks without feeling miserable.
3. A list of 20 free or nearly free things to do.
4. A meal plan approach that uses what's in the cupboards.
5. A short weekly check-in to track how it's going.
