A family budget usually fails for one boring reason: it asks you to track everything.

Groceries. Gas. Soccer fees. The random Target run. By Wednesday you are behind, you feel like you already blew it, and the spreadsheet gets closed until next month.

That is not a discipline problem. That is a design problem.

A budget that sticks for a household with kids needs three numbers, not fifty categories:

• In: what actually hits the account this month

• Must: rent, food, insurance, minimums — the bills that would hurt if they bounced

• Don't touch: a small amount parked so a flat tire does not become a credit card

Everything else is leftover. Leftover is allowed to be messy.

If you only do one thing this week: sit down on Sunday, write those three numbers on paper, and stop adding categories. Complexity is how families quit.

That is the whole idea behind BareEssence Books. Short. Usable the same night you read it.
