I understand your dream. I would like to one day sail a very long distance, but I am taking several years to completely understand what all sailing can do to you.
Remember that you don't have to cross an ocean to have an adventure, come down one day and I'll show you how much fun it is just to take a 3 hour sail to the islands around here. The sights are much prettier when it's not just water everywhere
Just food for thought- you don't always have to run before you walk.
