Dude, you stick around too long and you'll find a bird to settle down with, you'll pop out a sprog or two, then you'll NEVER get a chance to see anything of the rest of the world.
Trust me, get out there while you're still young enough to have fun with it!!
I'm pushing 40 now and would give my left testicle to have the opportunity you've got dropped in your lap!!
I had to join the Navy to even come close.
Your objections to going can be countered pretty quickly.
Job - you've gotten one, you can get another.
Friends - I've had so many friends in my life that I couldn't find now if I tried. There are very few people not blood related to you that would even try to keep in touch if you moved over there. The rest aren't friends, they're drinking buddies. They're a dime a dozen and can be found/replaced in a heartbeat. True friends wouldn't hold you back from an opportunity like this. They'd be stabbing you in the back to take it from you!!

LIFE - it's what you make of it. It can either be confined to a tiny little point on this great big globe, or it can be spread all over the place and enjoyed to its fullest. Your choice.
I know what mine would be in your shoes. And it wouldn't leave much time for making a reply to this post between stuffing travel bags......
