How is Odysseus humbled on his way home?

After being shipwrecked due to the wrath of Poseidon, Odysseus winds up on Phaeacia. There, he is washed up on the shore, naked and vulnerable. He lies down on a bed of dirty leaves, which is about as humble as you can get, especially for a great warrior-king like Odysseus.
Odysseus only got into this mess because he arrogantly taunted Poseidon's son, the Cyclops Polyphemus, after he blinded his one eye and escaped from his evil clutches. His hubris has got him into trouble; from now on, he needs to be humble. Thankfully, Odysseus's divine protector, Athena, is there to keep our hero's feet firmly on the ground. Once Odysseus arrives back on Ithaca, the goddess disguises him as a beggar, and Odysseus must show humility in maintaining this disguise until the time is right for him to reveal his true identity.
However, this is easier said than done, for when Odysseus rocks up at the palace, he's subjected to verbal mockery and physical abuse, not just from Penelope's suitors, but even from a beggar—a real one. For a proud king like Odysseus to be insulted in this way—and in his own palace too—must be unbearable. Somehow he manages to maintain composure, biding his time and remaining humble until the time comes to settle scores.
