Its interesting that you post this now, because very recently I went through the same experience. My life changed in many ways, and I lost track of my goals, my mission, even my own ideals. After some searching, I came out stronger for it, and redefined what matters in my life, and what my presence is all about. For me, it was all about altruism, and it will continue to be so, in small or large ways, throughout my life. Its a wonderful feeling to know exactly who you are, and what you want to do with the rest of your days, and I wish you the very best of luck finding those answers for yourself.
