I read this yesterday and have started the no spend day challenge. My rules are:
- Achieve as many as possible no spend days (NSD) and low spend days (LSD) in a month.
- Rent/ mortgage, utilities, medicines, food and petrol are allowed.
- Unnecessary extras will be counted eg coffees out, magazines, toiletries, taxis, buying lunch out etc.
- Planned spends eg Christmas presents, socialising are allowed. It's always good to stay in budget though.
Add your own rules if you like!
