The question is well posed and it's clear you love to write. However, are you a natural writer? I can help you with this question of "naturalness" by telling you about my own experiences.
Every human being is wired for language and he or she has a certain level or degree of competence to speak and write. We all do, but some of us are "naturals." I discovered to my amazement that I was a natural writer many years after I had already graduated the university with an advanced degree in physics. After the collapse of the Soviet Union, many of us young scientists lost our jobs and began other career pursuits.
I was lucky, maybe even talented, for I entered film school in my forties beating out many other applicants. What was it inside myself that out shined hundred of aspiring young filmmakers? I still didn't really know about my natural writing abilities at that time. Then, out of the blue, a kind lady professor showed me my true nature; while I attended her large class on the history of photography. There were fifty of us.
I was already studying cinematography in film production, with the idea of becoming a director of photography; when she held an in-class midterm where each of us had to write an essay on some predetermined topic about photography. And when she returned the following week with the graded essays, to my bewilderment, she had picked out the top two outstanding essays, one of which was mine.
Truly, the two styles of writing were completely different, my younger counterpart was logically structure and systematic, while my own way of writing is deep down in the gut, so to speak, and highly intense and personal. In fact, the professor commented that there are well trained writers, skilled in every detail, like my counterpart; and then there are the gut wrenching types, born "naturals," like myself, able to write in an imperfect style, sometimes even with grammatical errors, but still most highly communicative and effective. That me, for when I write, I really and truly write my guts out, as my hand writes, it writes me!
Are you one of those "natural" writers, Jenna? If so, go for it; and don't wait twenty five years to find your soul, especially based on the decisions about money and breaking into the industry.
Remember this, if anything: "The hand that writes, writes me." If I were you, knowing that I'm a "natural," I'd go for it big time.
