How does Ged decide what course to follow?

Ged, the protagonist of Ursula K. Le Guin's "A Wizard of Earthsea," decides his course based on a combination of instinct, personal experience, and the wisdom imparted by his mentors. Initially driven by ambition and a desire for power, he learns through his mistakes and the consequences of his actions. Ultimately, Ged's journey toward self-discovery and balance leads him to choose a path of humility and responsibility, embracing his identity and the interconnectedness of all things. This transformation guides him in making choices that prioritize understanding and harmony over mere ambition.
