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 10 years and it becomes $9,144, which is about 5.4 months of median US rent.

Interest does the second half of the work

Of that $9,144, you personally put in $6,000. The remaining $3,144 came from interest — money you did not earn by working.

What one skipped day costs you
