What are the motifs in Tracks by Robyn Davidson?

Personal growth is a recurring idea in the story. The journey is one of the most ancient themes for stories and lessons. Some journeys are through literal terrain, while others are in the spiritual realm, but they are often associated with personal growth and discovery. Usually, it is assumed that the journey will include great peril and trials, and the harder the going, the greater the perceived gain in adventure or insight. Robyn's journey is both a geographical and a spiritual one.
