God never said that you will live an average or unfulfilled life. You and the people who programmed your mind ‘assumed’ your worth, ability and deservingness. You have the same brains and ability like the most successful ones have. Only the circumstances are different and I can assure you that your circumstances are not the worst.
You don’t know who you are; you just know what they’ve told you about who you are!
Are you a fortune-teller? A clairvoyant? If not, why anticipate the worst for yourself? We predict events will turn out in a negative way because our self-beliefs are limiting.
