It is also essential to effectively manage our finances. When we go out shopping, try to leave the credit card at home and do not spending money for the luxury goods that we are not afford to it. For the bill settlement, we should pay double for the minimum amount if we can afford because it could cover the interest and pay the balance more quickly. Indeed, the most effective way is cut off the credit card but it is advised that save one card for emergencies.
