What do I want to know/learn about writing? (revised)

I would like to know how to write in different forms. And whats the perpose of writing in each individual form, also how each form differs from the other. I exspect to learn how writing can possibly transform into a career. Also I would like to learn how I could mingle writing into my Psycholgy major. I would like to learn of renoun writers that I could research for knowledge/inspiration in reference to writing. I would also like to know how writing is necessary in regards to my Psychology major, "what role does writing ultimately play?" I would like to learn how I can further articulate myself in my poetry, (things that I write outside of school.) I would like to find out is writing possibly something I really want to do. I would also like to know if there are other peers that may share the same desire (love) for writing that I do. And if I may have the ability to write professionally.
