Here's one way to sample living in the big wide world jp. Apply for a job at Butlins if you've left school or will be doing very soon.
The advantage to that, is that you'll meet lots of new people, have a job, get paid and have a roof over your head. After that, you can return home, hopefully in pocket, and then apply for other work - with proof of your experience. It costs a LOT to live decently nowadays, & because you wouldn't be able to afford to buy for a few years yet, the more qualifications & work experience you gain, the better your chances. Good luck.
