Beware of the duality of this question because as you answer this question you are also answering the question, “Who am I not?” You are constantly solidifying your identity. You are a happy person. You are a sad person. You are rich. You are poor. People go around saying what is good and what is bad, what is right and what is wrong.
Some of these beliefs that you have defined for yourself could be holding you back from the person you want to become. The real questions is not “Who am I?” the real question is, “Who do I want to become?” and “Who do I not want to become?” These two questions will guide and unlock doors for you.
