Graduating High school.

Well i'm scared about graduating high school because now i have to do things to be successful. Like i know what i'm gonna be but i heard its really hard to find a job. i want to move out of my house once i'm 18, which its gonna be in a few months but thats gonna take alot of work, its my choice though, i want to move out to learn how to live by myself, i know how to cook clean and all those house things you need to know but now i want to have my own money, and work for it with a job i want after i graduate from college.
