What this actually means

The habit is small. The total is not.

$20.00 a day feels like nothing — it is about a new smartphone a month. But run it for 1 year and it becomes $7,452, which is about 4.4 months of median US rent.

Interest does the second half of the work

Of that $7,452, you personally put in $7,300. The remaining $152 came from interest — money you did not earn by working.
