Honestly? I think talking and thinking about becoming a novelist is much, much easier than actually being one.
But if writing is your all-consuming passion, if it's what you live for, if you cannot wait to get home from school to write more, and more, and if you think your life will end if you cannot write down one more story, one more plot development, one more character's growth and change, then yes maybe, you will be that artist one day whose literary prose I cannot wait to devour!
Have you joined a writer's circle yet? are you looking into classes? Does your school have a literary journal that you can submit prose and poetry to for review and feedback... and maybe see your work in print that way?
Are you looking into schools with good English programs? And MFA in Creative Writing programs? Some colleges have "real" some even pullitzer-prize winning authors in residence... Imagine taking writing classes from THOSE !
Steps like that... reading good books and writing all the time, finding your "voice", submitting work for feedback and criticism..... will help you on the road to working towards your dream.
