Look for ways of saving money on expenses and eliminating non-essential expenses (entertainment, cable, cigarettes, shopping).
Refrain from using your credit to subsidize your income.
Deposit part of your income into a savings account to meet emergency expenses.
Know your priorites. Allot enough income for the essentials (shelter, utilities, food, medical, savings).
Make your spending habits consistent. Large expenses should be pro-rated over a period of time.
