I’ve been astounded by the number of people involved in investing and finance who have no clue about the rule of 72.

There’s a video here of a dad explaining the concept while his son applauds.

It’s very helpful to understand the rule, and to realize that when someone offers you 100% returns over 10 years, that the returns are reasonable, but not great, and that 100% returns over 20 years borders on a scam.

Think about it.
