My brother moved when he was about 20, he went to train as a nurse.
He married a woman from Devon and they are happy. They have three children, the youngest is at uni but the older two have had to move for work.
I like to visit but I couldn't live there for a few reasons.
Its so white, I was wandering around truro one day thinking, "What's wrong" then realised I hadn't seen anyone who wasn't white all day.
That means you don't get many (any) sweet centres, sari shops and no Jamaican take away.
Actually I looked at 'just eat', Truro has bout 15 places and 10 are kebab shops. My area has 160.
It also takes ages to get anywhere, there are no motorways and the trains all stop at every station.
Yes it is beautiful and has loads of fab beaches but it can also be wet and miserable.
As teenagers my brother's children found holiday jobs easily in hospitality and where more staff were needed for the summer, but waiting tables included working Xmas eve, day, boxing day etc.
As I said my brother loves it and lives there, I love it to visit but couldn't live there. Have a good think about what work you can do, and nanny/childminder is probably not going to be available.
