The main disadvantage of a credit card is that some people fall into the trap of thinking their credit card(s) is an extension of their income. The credit card becomes a crutch to make up for a shortfall in their budget and at first, it's not a big deal especially with a 0% interest introductory offer, but at some point the reality hits that not only is there not enough money to meet expenses, there isn't enough to even make the minimum payment on the card.
The temptation of purchasing something that you really can't afford at the time sometimes becomes so strong and overcomes any common sense and a person ends up mortgaging their future income for immediate satisfaction without considering the ramifications of making such a purchase.
How to overcome this? It's actually very simple. Treat a credit card like a debit card. Only use it for necessities and things you would have paid cash for if you didn't have a credit card and only when you have the funds available to make a purchase. Then, pay the credit card(s) in full each month with those funds and never carry a balance.
