📜 Rules for building wealth

A few habits do most of the work.
  • Pay yourself first. On payday, move a fixed amount to savings before you spend.
  • Then spend guilt-free. Whatever's left after that transfer is genuinely yours to spend.
  • Build a buffer first. Save 3 months of costs before anything else.
  • Make it earn. Keep savings in a high-interest account so compounding grows it for you.
  • Clear pricey debt first. Paying off costly debt earns more than savings do.
  • Bank your good months. When a month leaves something spare, top up a box instead of letting it drift away.

💰 Savings Boxes

One box for each thing you're saving for.

📈 What it becomes

in 5 years

Good things to save for

  • A 3-month emergency cushion.
  • A holiday you don't have to put on a card.
  • The next phone / laptop, bought in cash.
  • A deposit, a car, or just future-you's freedom fund.
