There are a multitude of ways you can make good money, but I'd say the quickest way (but not the easiest way to do it) is through studying a STEM degree in college and getting a job in a STEM field. STEM stands for Science, Technology, Engineering and Mathematics. By studying a field like Computer Science, Engineering, Mathematics or Economics, it enables you to either find a great job after college. Of course, internships at certain firms during college will help you to get there.
There are other ways to make good money after high school which does not include college, but since this is the path I am familiar with, I have given my 5 cents here.
Best of luck.
