Who Am I

I have these moments in life where I ask myself...who are you? I perceive myself as an introvert who wishes to avoid challenge and new experiences. And yet, I look at my life and realize... these are not the actions of one who avoids challenges. I'm taking on new challenges, pushing myself to limits, and exploring the world that is outside of my comfort zone. I'm doing new things at 34 that I never would have thought of doing in my 20's. So again I ask the question, who are you and what have you do with.....me?
