Hm - well, I love writing so I'd like to write novels, screenplays, dialogues, and other literary works which hopefully many people would watch/read and enjoy - but the main purpose would be the fulfillment of my own being. I guess that being a writer is something I'd do creatively as a hobby rather than professionally as a living (I might make money from my works though)
My ideal career would be becoming a professor of some sort; maybe history or philosophy. I'd love to get my Master's or a Ph.D in one of my favorite subjects.
This does raise an interesting philosophical question ... would that make me a Writer, a Professor, or both at once?
