How is odyssey clever and able to meet challenges

Odysseus is the epic hero because he never forgets his goal, to get home. Even though he is married he sleeps with the goddess Kalypso (I know, such a sacrifice) He leaves this beautiful island on a rickety raft only to be near drowned by a pissed off Poseidon. Really the island he was on was practically a paradise where he could get all the sensual loving and fruit that he wanted. Still he longed to go home to all his chores and a nagging wife; now that's dedication.
