What careers do you think I should consider?

I’m 14, a female. I’m staying at school until I’m 18 because I want to get a good job. I’m planning to go to university, maybe in London or Oxford. I’m above average on English, Science, Drama, Music, Art and I.T. and I’m average in every other subject. When I’m older I want to travel the world, bungee jump, sky dive, surf and other things. Then I want to open up my own farm with a B&B, cafe and giftshop. But I need a good job so I can afford to do all these things. What careers do you think I should consider?
around £10,000 – £50,000 please.
Also what job should I get when I’m in university?
Sorry, but I’ve got a phobia of hospitals.

I don’t know why because I’m okay with blood.
