Week 1 · 45 minutes
Optimize Your Credit Cards
Turn the most feared financial tool into your best one.
The big idea
Credit is not the enemy — invisible interest and passive habits are. Week 1 is about making your cards work for you and cleaning up your credit history.
A strategic framework for deciding whether to pay off debt or invest — categorizing debt as high or low interest based on your age and the specific type of loan.
Why credit matters more than you think
Your credit score quietly prices the biggest purchases of your life. A strong score can save tens of thousands over a mortgage, and it takes months — not years — to fix the basics.
- 35% payment history — never miss a due date
- 30% amounts owed — keep utilization low
- 15% length of credit history — don't close old cards casually
- 10% new credit, 10% credit mix
Rules for using cards like a rich person
The goal is boring, automatic excellence: pay in full, on time, forever. Rewards only count if you never carry a balance.
- Automate full-balance payments so willpower is never involved
- Ask for a lower APR and fee waivers — scripts work surprisingly often
- Request credit-limit increases to lower utilization
- Never chase rewards with spending you wouldn't do anyway
How to use credit cards like a rich person.
Digging out of debt
Active learning check
In one sentence: what is your current total credit card debt, and what APR are you paying on the largest balance?
If you don't know, that's the answer — write "I need to look it up tonight" and do it.
