A credit card is either one of the best tools you own or one of the most expensive mistakes you'll ever make. It's the same card. The difference is whether you understand how it works. This is the crash course nobody gave you in school.

In this episode, Mary Beth runs a crash course on credit cards, drawn from her years on the phones for a bank helping people understand their bills, finance charges, and what happens when they don't pay on time.

We cover:

→ How a credit card actually works, and why treating it like a short-term loan changes everything

→ How the institutions make money off you through interest and the minimum payment trap

→ How to use one the smart way, treating it like a debit card and setting up autopay

→ How to build credit without getting burned, including the 30 percent rule

→ Why the boring wins, paying on time and in full, matter most

Same card, two very different outcomes. It's all in how you approach it.
