I believe that the first phase of Liz's journey has been really about discovering who she really is and what really makes her happy....and trying to do it without a man in her life. By the end of her time in Italy I believe that Liz was well on her way to becoming an "independant woman." I like to think that as Liz continues her journey she will only become stronger and finally get in touch with her REAL self.
Right now I think my word is "dependent." Because right now I'm pretty dependent on a lot of things just to keep my world turning. I really don't think that it is possible for just 1 word to define you for your whole life. I think that for each small chapter there may be a word but by the time your life is over those strings of 1 word become a GIANT string of MANY words that defined you during your lifetime.
