The most important step to getting out of debt is to understand what behaviors or circumstances caused the debt to begin with, and then focus on changing those behaviors first. This means that if you have incurred a lot of credit card debt because of undisciplined spending habits, you must immediately attack the root cause of the debt, in order to reduce your debt. If you incurred a debt because you obtained a mortgage for more house than you can afford, you must find a way to sell the house without incurring a loss, and purchase a smaller, more affordable house.
When trying to pay off high credit card bills, always tackle those with the highest balances first.
