Distinguish between Wants and Needs:
You will save a ton of money if you don't mistake wants for needs. Needs are pretty simple to identify–those items that are necessary to sustain: Shelter, food, clothing, transportation. Wants are those things that enhance or possibly improve our family life. A car is a need. Unless necessary for your business, a $40,000 Sport Utility Vehicle is a want, even if a lot of people don't see it that way. Have you ever heard (or said) "I absolutely need...?" when the actual meaning was "I really want?" This is not to suggest that you shouldn't be able to have the things you want–only that to delude yourself into believing that a want is a need–and busting your budget in the process–is a recipe for financial disaster.
