I'm still considering it, but it seems unlikely. I wouldn't know how to survive for very long on my own like that, and I'd need to find somewhere to live until my first wage packets come in - not easy on jobseeker's. I've no experience of travelling either.
So, if I get offered a job earning more than 16k in England, I'd think about it some more. Last job I applied for here yesterday was for 12k. It was the first one I've seen in months.
