The Signature that changes life as I know it

Right: today the contract came by DHL. Looks good and about the same as the draft versions I received earlier. Sign it, say a little prayer and send it. Cool, so now I've officially resigned, signed a new contract and lodged an application for a visa at the Sydney Office.
Worst case scenario: I don't get the visa, bought my one-way ticket for nothing; lose job, wife leaves, dog dies and car burns.
happy that I don't own a dog right now…
Best case scenario: I start a new and exciting life in about 7 weeks.
