@EmilyCharlotteCooledge Publishing has been a mixed bag for me, as far as difficulty. My very first publication about the Beatles - in the Village Voice (a New York City) - was easy: I sent in a Letter to the Editor, and the next thing I knew the letter was published as an article, and I got a check for $65 in the mail! But it took me five years of going to conventions and meeting editors to get my first science fiction novel published - The Silk Code.
I got an agent to negotiate a better deal for me on that first novel. But I had already made the connection with the editor on my own. In retrospect, although the agent did get me a better deal, he didn't do much for my other contracts. Meanwhile, he happily collected his 15% - and 20% for translations. I left him after 10 years, and, in retrospect, I should have done that much sooner.
I love biology! For a while, when I first got to the City College in New York, I wanted to be a bio-chemist. But I didn't enjoy getting into class at 8am in the morning to dissect a fetal pig in alcohol :)
But I studied evolution and DNA for my doctoral dissertation, "Human Replay: A Theory of the Evolution of Media," and that knowledge served me in good stead when I was writing The Silk Code, which has the tagline "DNA is the ultimate dossier".
You can have a really good life being both an author working in another profession - whether teaching, research, etc. So I'd recommend that you continue your writing as well as your university degree,
"The Heist" already caught my eye, and that's indeed the next story of yours that I'll be reading!
