Two Sheds, high five fellow expat buddy!
I'm an Australian but I've lived 8 years in Thailand and am currently living in the Czech Republic, and echoing what Two Sheds has said - if you have the urge, go go go! Traveling and living in foreign cultures has been the most fulfilling thing I've done. Also, don't let little things like not speaking the language hold you back, that's all part of the fun.
As for me, I'm not done yet, I've no idea where I'll be in the next few years and I'm open to anywhere, provided it isn't the USA. I have no urge to go there for some reason.
