Generate a 30 Day No Spend Challenge Tailored to Your Weak Spots

Generic no spend challenges fail because they ignore what you actually overspend on. This builds a 30 day plan around your specific weak spots, with a real definition of a no spend day, a few planned treats so it stays livable, and a weekly check-in to keep you honest.

<task>
**Generate a structured 30 day plan:**
1. Define what counts as a genuine no spend day versus an allowed essential (groceries, bills)
2. Build in three or four small permitted treats across the month so the challenge is realistic, not punishing
3. Address each weak spot directly with one specific substitute or barrier (for example removing a saved card, batch cooking)
4. Include a short weekly check-in prompt to track progress and adjust
