Final answer:
Odysseus needs to eliminate greed and excessive curiosity to get back to Ithaca. He shows personal growth as a hero by exercising self-control with the sirens.
Step-by-step explanation:
In order for Odysseus to return home to Ithaca, he needs to eliminate the behaviors of greed and excessive curiosity. Tiresias advises him to show denial of himself and restraint of his shipmates. These behaviors are exemplified by Odysseus' previous actions, such as his impulsive desire to explore the cyclops' cave and his obsession with hearing the siren song.
However, there is evidence of personal growth as a hero in how Odysseus approaches each encounter. In the cyclops' cave, he acts impulsively and without self-control. However, when faced with the sirens, Odysseus exercises self-control and resists their alluring song. This demonstrates that he is learning to resist temptation and exercise restraint.
