First, track your spending and expenses for the next 30 days. You can begin by recording all your purchases on a weekly expense report worksheet that you fill out each day. Save your receipts from each purchase and then record a description of the purchase, the amount, its category, and how you made the purchase; whether by cash, check, or credit card.
