"Ulysses" details Ulysses' intense dissatisfaction and boredom on his island home of Ithaca. The poem is a monologue spoken by him, where he not only expresses his discontent, but also describes his desire to keep sailing. He's getting older and doesn't have a lot of time left, so he wants to get busy living rather than busy dying.
The poem concludes with his resolution to "strive, to seek, to find, and not to yield."
