I need a list of things i need to study ready for adulthood...?

When im 16 i am moving out with a friend (Please do NOT start going on about how im going to do this because this is NOT the question)
Im 14 atm so i have a good 2 years of studying the values of life.

What i am going to start doing is making some plans and studying things needed in everyday life in adulthood... With a little help from YOU!

I have a book and im going to put everything in their... i need a list of things that are important that i should study...

Example
--------------
Cooking - Study how to cook, some basic recipies, how to work a basic oven.

So please list some things i need to study like the example and ALSO some things in that category that are important to know and learn.

Any facts also appreciated.

Thanks x
