You are unique. You are the only person in the world who is exactly who you are. The Almighty has not made anyone else like you. Only you have your unique genetic makeup and your unique life circumstances. No one alive now, and no one who ever lived before, and no one who will ever live in the future was, is, or will be just like you. You are the only person in the world with your unique positive qualities and challenges. You are the only person in the world who has your particular life mission.
You, like everyone else alive right now, are a work in progress. You have a multitude of positive choices you can make throughout each and every day. Choose life! Choose positive thoughts, words, and actions. With every positive choice you make, you build yourself. Keep making positive choices.
(From Rabbi Zelig Pliskin's book: "Building Your Self- image and the Self-image of Others" (Artscroll) Introduction)
