Ithaca, the famous poem by Cavafy expresses this idea beautifully.
Cavafy is referring of course to Odysseus, one of literature's greatest heroes, who fickle gods condemned to wander for twenty years.
Here's a link to a fine reading by Sean Connery (!) with music by Vangelis.
Let's keep Ithaca in mind as we embark on the adventure of change.
Odysseus' journey took twenty years.
Ours may take as long, or even longer.
But think of all we'll learn & experience.
