You are your own person. You have an identity. You know basically what you are all about. People have ideas of you, they differ from person to person, but generally people agree on certain common traits about you, certain features of your personality, all that makes up who you are.
Given that you can’t change your physical appearance unless by some drastic form of plastic surgery, can you change your persona? Be the person that you’ve always wanted to be. Or more so, become a totally different person! People change over the years but how much really changes. Can you change to the point of being totally unrecognizable to someone who hasn’t seen you for years? Does this same thread run through you even as the circumstances around you change and your experiences change. Or will you always be the same person. Is there a constant and is it definite?
