What this actually means

The habit is small. The total is not.

$16.44 a day feels like nothing — it is about a new smartphone a month. But run it for 1 year and it becomes $6,125, which is about 3.6 months of median US rent.

Interest does the second half of the work

Of that $6,125, you personally put in $6,000. The remaining $125 came from interest — money you did not earn by working.

What one skipped day costs you
