I think before you finish high school, you'll want to make sure that you research the Colleges you're considering to make sure they have a program that meets your needs. I'd look to make sure they have a writing related major, the strength of that major, if it seems like they have many well regarded published authors as faculty, and the quality of their literary magazine or newspaper. Many colleges with good programs will have a writing minor as part of a Major in English. Writing also encompasses many different career paths, whether you want to be a fiction writer, screenwriter, journalist etc is going to shape your decisions in which college to attend if you've made that decision. Once you've declared a major, most colleges require you to take a pretty broad amount of core curriculum classes, including several requiring you to read and analyze a significant amount of "classic" books. Reading well, and learning from great writers is extremely important to becoming a good writer, but it does mean that most of the classes you take at least your first year of college will be dictated by the University. In these core classes, I'd try to sign up for classes that have professors you're most interested in, or who are published author's themselves. Take lots of writing workshops, whenever you have the opportunity to, as that's what will most improve your own writing. Studying writing is really something you get out what you put in, so as much as you can, really try to foster relationships with professors you connect with, see if they can connect you to valuable experiences or internships, and absolutely get involved with the campus literary magazine or newspaper. The more actual experience you get writing, and publishing that writing in college, the better suited you'll be to pursue your writing career upon graduation.
