If you are not maximizing your potential, it means you are living a lesser life and far from full capacity. No one access the life God prepared for him without growing to understand who he is and shaped to become. You are rich by what you possess and not what you don't have. Any prophecy given must be an addition to what you have received and discovered. If John knew he was Elijah to come, he would have done a lot more. Don't give a No or Yes answer if you are very sure of the situation. To be an overcomer, you need the gifts of the Spirit. You will be given a new identify of you don't have one. You must know yourself, calling and purpose more than anyone knows.
