“Never use a credit card for credit. The only kind of credit, or debt, that is acceptable is debt to acquire something whose exchange value is extremely likely to increase, like in a home. The exchange value of most things diminishes or vanishes the moment you purchase them. Don’t be in debt to losers.”
