First thing first you should learn the basics
1) How to cook
2) How to clean
3) How to wash, dry and iron clothing
4) How to manage finances
5) How to manage grocery shopping
You will also be responsible for getting yourself out of bed, abiding by property rules (no pets, no noise after x) and usually setting up utilities and internet services (unless otherwise included).
Do you think you can do that? It's a lot of work.
