After High School, studies still not finished. Now is your choice, make money or don't make money? This question is so easy, make money I think, what to do after High School? what are my plans for after High School? How I can make money?
After you finish your school, you need do plans for after graduation, If you want college or university, how you can do it, think about what job you want try, and how more quickly you do it more chance you have to make money.
My advice for you is, do your plan before High School and FOCUS IN WHAT YOU WANT TO DO.
