If you just pay the minimum on credit-card bills, it will take you 20 years or more to pay them off. That means you'll pay more than five times the actual debt in interest. Watch where you borrow. But that can be dangerous. You could lose your home, or fall short of your investing goals at retirement.
Some debt is good.
Borrowing for a home, college or a car makes good sense. Just don't borrow more than you can afford to pay back. Some debt is bad. Don't borrow for things that you consume quickly, such as clothes, meals, vacations. There's no quicker way to fall into debt hell.
