Live each day, each second, each morsel, to the fullest. Do what you want to do.
What a gift, at twenty-nine, to have had to face myself and ask: what do you regret, now that your life may be over? I live now in a manner that will allow me to answer that same question - at forty-nine, sixty-nine, eighty-nine, whatever age - "NOTHING!"
I'll tell you the honest truth: I would not undo this gift of perspective, even to have my breast back.
I know, now, what is important, and what is not.
