When It's Real Money

Somewhere in the last year or two, an account showed up with only your name on it — a checking account, a first brokerage account, maybe both.

The first paycheck is often the first confusing number of adult life: you did the math on your rate and your hours, and what showed up is smaller.

Somewhere around now, offers for a credit card start arriving, or a phone plan, an apartment lease, or a car loan asks about your 'credit.' All of it points at the same underlying thing: someone else's money, lent on trust, with a cost attached for the lending.

Borrow a thousand of anything and you'll eventually pay back more than a thousand — that part is expected.
