The most important of these is automatic savings. Open a savings account, and set up your checking account so that you automatically transfer a set amount each month into your savings account. You don't have to transfer much money _ start with whatever your budget can afford. But making this automatic (and then resisting the urge to spend the money impulsively) will get you on the road to long_term savings.
A personal or household budget is an itemized list of expected income and expenses that helps you to plan for how your money will be spent or saved as well as track your actual spending habits. Though the word budget has taken on a more negative connotation over the years invoking an image of pinching pennies or limited spending, a budget is really just a tool_and a great tool at that_to gain better and more accurate insight into your spending habits.
