I don't want to be the party pooper here but heck why not go? I have emigrated (after being very sure I wanted to

) Yes ofcourse it's wise to go for say 2/3 weeks before making the final jump. (doh) Just to see how you like it. Emotional bagage etc
will follow make no mistake about that. But if you're young jeez why not have a go while you can? Plenty people stuck in one place thinking oh boy whish I went when I could before babies, mortgage, you name it

Sometimes it's better to stay put but sometimes it .... is .... time! I'm sure you know if it's a runaway thing or the jitter better get going because have to thing. Let us know what you do. (And do sleep on it okay? I'm not advocating jumping the gun etc etc)
PS: Liara that's a beautiful piece right there. thanks for that
