For me, the dream is all about adventure, freedom, and being really alive.
Although I like seeing the sights wherever we go, I think it's the sense of adventure coupled with the freedom to do what I want to do with my life, seasoned with a pinch of adrenalin that makes it all worthwhile.
It doesn't matter whether I drive down a hundred foot sand dune, sail through Pirate Alley, or voyage across an ocean, I still get the feeling that I am really alive and am accomplishing something important to me. I'm living my dreams, and although it's a lot of work, costs lots of money, and spends the currency of my youth, that doesn't matter, because I'm doing what I want with my life as I live without regrets.
