From a Self-Coaching perspective, it's not possible to answer this question. Not because it's illusive or complicated, but because who you are isn't a stationary concept like a snapshot or a portrait painting. Instead of trying to pin down the "who" you are, think instead of "what" you're becoming. Every second of every day you, your persona, is evolving, changing, adapting. The real question is what is the direction of this change? Not sure what direction your life is headed? Simply begin by taking a closer look at your here-and-now actions and the choices you make. And if you don't like what you see, then start making better choices! One choice at a time.
