Have an Answer?
I've been a published writer of fiction for 40 years and have taught fiction writing on both the university and arts high school levels. Your question is so broad that it's hard to know how to begin. READ, READ, READ fine fiction (I'd be glad to offer suggestions) and simply begin to WRITE. Majoring in English is always an enormous help. Be brave, be patient, and see if you 'want to be a writer' or you 'want to write' !
