What this actually means
The habit is small. The total is not.
$10.00 a day feels like nothing — it is about 5.0 months of streaming services a month. But run it for 1 month and it becomes $300, which is about 5.0 months of streaming services.
Interest does the second half of the work
Of that $300, you personally put in $300. The remaining $0 came from interest — money you did not earn by working.
