It just struck me... the easiest way to tell the close ones about leaving is... (I'm gonna leave you some seconds to thing about it)... Yeah, you probably guessed it if yo already read
this post.
Using baby steps is the way to do it... if you'll just wait until the final moment to bring it up, you could end up giving you old folks a heart attack. I didn't think about this at the beginning but as time passed it became more and more obvious. In fact the earlier your bring it up the better it is (you could even get their support).
So, it's quite simple, randomly start talking about Oz, about what you think it's cool about it. And keep on doing it until you encounter resistance, then just drop it. After some time start talking about it again. When you do this try to gradually get closer to the idea of moving there.
And people will eventually get accustomed to the idea that you're talking serious business.
And this behavior can be used almost everywhere and anywhere (as long as time permits it).
The only drawback that this particular situation has is that if you'll start talking to new people about this from the start some of them will be really careful about committing when it comes to you. Don't worry about it, it's only a few that react in this particular way.
Hooroo!
