Most people know when they’re struggling financially. Especially when you pay for everything with cash or debit. When the money runs out, you have no choice but to stop spending even if there are bills still to pay.
Credit card debt is different though. It can distort your impression of your financial situation because you’re not paying for things outright. And when you consider the fact that you’ll most likely only need to make a monthly payment smaller than the amount you spent, it’s easy to see how buying things on credit can get out hand quickly.
