What is Janie seeking out of life?

Janie spends some time considering her future. She realizes that it is time for her to embark on her journey to the "horizon," a journey where she hopes to meet people rather than just gather "things" as she has been doing so far in her life. She considers tending her grandmother's grave or searching for the mother that abandoned her, but she realizes that neither woman encouraged her freedom and her quest for the horizon.
