Immortal and then die...?
Honestly, how much time do you have? I'm a pretty ambitious guy - perhaps overly ambitious, but I prefer adventurous - so there are a lot of things I'd like to do. I certainly want to see more of the world (ideally, I'd like to have lived - at least briefly - on every continent), and I really need to learn a second/third/fourth language. It's pretty embarrassing that I left Korea only knowing a handful of terms (hello, goodbye, thank-you, don't do that!, etc.), so I'm determined to pick up the first language of anywhere I am in the future.
In addition, as I mentioned in another of your questions, owning a restaurant is certainly up there. My partner is very much against the idea (thank-you, Gordon Ramsay), so we'll have to see - perhaps we can negotiate and do some sort of cafe/bakery. She loves her baked goods, and as you know, I love my coffee...
And, of course - the dream of all Hubbers - I would like to be published.
Beyond it all though, I just want to be happy. And I certainly don't need to achieve it all for that (though I still intend to).
