A belief is your opinion about something - in this case your money. Maybe you believe saving money can help you gain security. Or perhaps you believe having a lot of money will bring you life-long happiness.
Think about your money beliefs. Are they based on facts or based on fiction? Having some money in a bank account will probably give you a more secure feeling about your financial situation. However, money alone is seldom the key to life-long happiness.
You will use your money more wisely if your beliefs are based on facts.
