Abundant thinking is about being grateful for what you do have rather than focusing on what you lack. It involves having no hard and fast expectation of what you will receive based on some egotistical notion of what you deserve out of life.
Abundant thinking is a form of positive thinking. It is about creating a mindset of positive values that allow you to perceive your life as one of abundance, not one of deficit. It teaches you to flip your mental attitude coinfrom negative to positive and appreciate how much you have in your life to be grateful for.
