Odysseus' hero's path

From books one and two Odysseus doesn't follow the hero's path. Odysseus is just gone and dissapeared form the face of the earth and no one knows what happened to him. First of all Odysseus has no speical birth, no call to advanture, and no belly of the whale. In the book Odysseus desides to go to war and then doesn't return. In other words he had no guide no call to advanture and no belly of the whale because he could have just not gone to war and the story would have never happened.
