I moved out and started university when I was 17. My brother and I shared a townhouse and a car. It was challenging learning to deal with money and so much independence, but fun!

Perhaps if you're worried about money and budgeting skills you could start now by helping your parents with things like the groceries. They could give you a certain amount and you would have to figure out how to get the most food for a week with the given amount. Exercises like that would have been really helpful for me.
