What this actually means

The habit is small. The total is not.

$1.64 a day feels like nothing — it is about 3.3 large pizzas a month. But run it for 1 year and it becomes $622, which is about a new smartphone.

Interest does the second half of the work

Of that $622, you personally put in $600. The remaining $22.48 came from interest — money you did not earn by working.

What one skipped day costs you

Skipping a single $1.64 deposit today costs you $3.55 ten years from now. Skipping one day a week costs you $1,302 over a decade.
