If you are a “glass half empty” person then you will run around thinking you don’t have enough time to get everything done. You will never have enough money, which might mean you overwork to earn more, or over extend on your credit card, for example. You will feel you never have enough energy, which means either your work or your family and friends never get the best of you. A shortage mindset like this focuses on our limited resources, leaving us feeling overwhelmed and short-changed.
