twenty years gone, and i am back again

on my own island.

as for my change of skin,

that is a charm athena, hope of soldiers,

uses as she will; she has the knack

to make me seem a beggar man sometimes

and sometimes young, with finer clothes about me.

it is no hard thing for the gods of heaven

to glorify a man or bring him low.

based on what odysseus says in the passage, what has he learned?
