The Biscuit Tin: Auntie Bisi's pay-yourself-first money system, workbook + spreadsheet

I landed in London in 1979 with forty pounds and a suitcase with a broken zip. Every Friday, before the landlord, a little went in a biscuit tin under my bed. That tin bought my first house. This is the same tin, cut into compartments, and it does the sums for you.

Type three numbers: your pay, your rent, the month you're starting. Auntie fills every tin, and anything spare goes in the tin with your name on it. Then ten minutes on a Sunday, with a cup of tea, and nobody can surprise you again.

Inside:

• A 36-page workbook, with my ten rules on one page each.
• The Reckoning, one honest hour that you only do once.
• The ten-minute Sunday Count.
• A letter for the week you want to quit.
• Four bonuses: the Paper Tin, the Five-Pound Start, Saying No Without Losing Family, and the Big Things planner.
• The spreadsheet, for Google Sheets or Excel. It has tins that fill themselves, a month view with Auntie's verdict, a "paid myself first" streak, and a Loans in Disguise tab for every pay-later you've been pretending isn't a loan.

Digital download. You'll get a PDF, and the spreadsheet link is inside it. General money education, not financial advice.
