Don't forget that when you shorten the term of the loan - the payments are higher. Another way to combat interest is to use as little credit as possible. Using credit cards is a fast way to pay A LOT of interest. Try to pay off credit cards as soon as you can and if you HAVE to borrow money - make sure that you are doing it because you plan to put that money to work for you. Don't borrow money for consumable items like groceries or restaurants. Only buy assets with credit.
