What this actually means

The habit is small. The total is not.

$3.00 a day feels like nothing — it is about a month of streaming services a month. But run it for 1 year and it becomes $1,118, which is about 2.8 new smartphones.

Interest does the second half of the work

Of that $1,118, you personally put in $1,095. The remaining $22.85 came from interest — money you did not earn by working.
