I am a big fan of the whole idea of writing down a (money) philosophy on an index card. The limited amount of space focuses the mind in a unique way. I wrote about the phenomenon a few years ago. Harold Pollack who created a bit of a sensation with his personal financed index card, which he turned into a book with co-author Helaine Olen, The Index Card: Why Personal Finance Doesn’t Have to Be Complicated.
Pollack, who is a professor at the University of Chicago, recently created a new index card focused on young (30 and under) adults. It has some overlap with his original index card, like the need for savings, but includes tips on spending and borrowing as well. As with all these exercises, everyone can take something away, even if you are well past your 20s.
