What motivates Ulysses to go on another voyage in the poem Ulysses by Alfred, Lord Tennyson?

is
motivated to go on another voyage in the poem Ulysses byfor several
reasons. Ulysses states:

Death closes all: but something
ere the end,

Some work of noble note, may yet be done,

Not
unbecoming men that strove with Gods.

As he compares his
current life with the great events of the Trojan War and his return home, he considers that his
life is being wasted. He is bored with Ithaca and feels that it is time for his son, Telemachus,
to assume the duties of rulership for which he has been trained. Ulysses himself has no real
purpose to stay at home when there is the possibility that despite his age, he might still
manage some last great deeds, giving a sense of purpose to the end of his
life.
