The very fact that we are calling this time an "odyssey Year" is interesting. The english major in me needs to explore this metaphor a little.
Odysseus didn't have an odyssey year, he had a 10 year journey after an already 10 year absence fighting in the Trojan war. All he wanted to do in the first place stay home with his wife and son. For him, a 20 year absence from his life is something he must endure. I think this is part of the reason calling young exploration an Odyssey is limiting. We may be searching for that home, not trying desperately to return to it.
I think you have a much, much clearer idea what the destination is now because of your journey.
