At first it may seem difficult to limit spending and stick to a budget, however there are a few practical changes that you can make everyday that will cut your spending more than you expect.  
Firstly, alter credit car behavior.  Start to pay cash whenever possible.  This will help you avoid making a purchase unless you actually have the money available.  If you decide to make a credit card purchase, be prepared to pay the balance off monthly.  This will save a lot of money through avoiding interest charges.  If you already have a credit card balance, then transfer to a card with a low interest rate.  Also, find a card that does not charge an annual fee.
