INTRODUCTION

English translation pending.

CORE DEFINITION

The snowball method expands a sample through referrals from existing ones, growing larger as it rolls. Its better-known financial form lists debts from smallest to largest and throws every spare resource at the smallest until it is zeroed, then folds that payment into the next. The mechanism is momentum: an initial small advantage keeps amplifying itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Order from smallest to largest: sort debts or tasks by size, not by rate. - Clear the smallest first: take the quick win that frees psychological energy. - Roll the payment forward: fold each cleared item's amount into the next one.

anchor

Anchor fast decisions

A cleared item does two things at once: it returns a payment amount that becomes available for the next target, and it delivers a visible win that sustains effort. Each subsequent item therefore faces more resource and more confidence than the last, which is the self-reinforcing loop that gives the method its name.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

List all debts or tasks and order them from smallest to largest. 2. Direct every extra resource at the smallest item until it reaches zero. 3. Fold its payment amount into the next item. 4. Let the momentum keep accelerating.
