The topic itself "who am I ?" is quite intriguing. Many people when asked "who they are" they will tell you who they want to be. Knowing yourself is very critical in a world where there is too much confusion. "Remember if you don't know who you are, you will always settle for less".
I personally believe that it is very important first to know your values,(what you value most in life), then pursue what you believe in. Your value never changes and it is consistent with your original authentic blueprint and design.
Everyone of us is very unique, no two people are the same. It is this uniqueness that gives us undeniable edge over  life. Remember that the awareness of who you are, is the greatness that dwells inside of you.
Never forget that you are the fountain of light, and inside of you is an infinite sea of possibilities that is ready to be released into the world. Trust and believe in yourself and watch the magic happen!!!
