Compare the choices of Romeo or Juliet with a Tennyson poem.
I would take the commitment that Juliet feels at the end of Act III the protagonist in Tennyson's poem, "Ulysses." Both feel that their current living conditions, the area they both call "home," has outlasted its usefulness. In Tennyson's poem, Ulysses feels that his life at home in Ithaca has lost its sheen and that he has to go back out into the world, away from his home, to find his own notion of self. Juliet experiences the same rift between her and her own home, finding herself absolutely committed to leaving her home after the exchange with her parents. For both, their identity is constrained with their presence in their homes. They have tied their subjective notions of self to something outside where they live. For Juliet, this is living with her Romeo. For Ulysses, this is the warfighting life and all the adventures that accompany it. Finally, both characters experience a sense of determination and commitment to make their subjective become reality. Juliet leaves Act III with a driving force to make her life with Romeo a reality or die trying, while Tennyson's conception of Ulysses is one where he commits himself "to seek, to strive, to find, and not to yield."
