I believe it has to do with finding your authentic self, feeling a real sense of hope as you enjoy what you do with passion and then becoming your own beacon of light. As an intuition expert and lecturer I've encountered many an individual in my life who did not know what their life's purpose was and in fact were startled when I asked the question.
"Man often becomes what he believes himself to be. If I keep on saying to myself that I cannot do a certain thing, it is possible that I my end by really becoming incapable of doing it. On the contrary, if I shall have the belief that I can do it, I shall surely acquire the capacity to do it, even if I may not have it at the beginning."-- Mahatma Gandhi
Some of us have been given gifts to lead, others gifts to write or teach and still others have gifts that share joy and laughter. Sometimes our gifts are a heavy burden but nonetheless, they are ours to behold.
