Money is defined as a current medium of exchange like coins and banknotes, as well as the assets and resources owned by someone. Money is needed for daily living expenses, relationships, and life plans. It affects standards of living, health, education, and self-esteem. Money functions as a lubricant and power in society, and brings freedom and status. Like oil, it can move resources to where they are needed. People are either spenders who lack regard for the future or savers who are shrewd investors and goal-setters. Proper money management is important for success through life's stages of dependence, independence and responsibility.
