We're thinking about this. No way in hell we can afford to go on holiday to Abu Dhabi, Malaysia, Thailand, New Zealand or Oz with 3 kids so the only way for us to know is to go there.
Our view is we could play it safe all our lives, maybe afford to go to France once in a while and generally camp around the UK or we can seize the day and do something bold.
I have a career that will only be helped by the move and we can come back after a year or so if it doesn't work out. We feel we owe it to the kids to actually see the world.
We'd prefer to do what Peter Duncan did with his kids but we don't have the BBC behind us and second to that would be working Tefl around the world or picking grapes (as if we could ever get the money for plane tickets together we'd have no extra cash on top). By going there to have a proper job that will boost my career we're committing big time but also will have the chance to explore further a-field whilst there.
But we have only the internet to tell us what it will be like.
It is terrifying and as much as I want this for us (one life to live and all that) part of me really hopes I get the great Assistant Head job just down the road so that we don't even need to move to Cornwall... but that is my borderline ASD worrying (watching the Big Bang Theory is an eye opener... I have too much Sheldon Cooper in me).
Do it! Be brave. One life to live. Have an open return ticket though. Don't burn all your bridges. Go for it! Live Life!
