I decided to pick a big, kinda scary, goal for my life. This purpose has grown over time, and I'm sure it will continue to evolve. But right now it's this: To help millions of people (including myself) become better writers.
Although I have countless interests in life (I'm basically curious about everything), the three main passions in my life have been (1) computer programming, (2) writing, and (3) teaching. These all began in earnest during my preteen and teen years and have shaped the course of my education and career.
I learned to program computers when I was ten years old, and this passion has carried me through most of my adult life by providing steady employment and enjoyment. It pays well and is rarely boring. My other two passions, however, have not been idle. My goal now is to transition my career away from technology (which, as much as I love it, does lose its luster after a few decades).
I started my first novel around age thirteen. I loved the process of inventing (and discovering) new characters and storylines, and mostly trying to piece them all together into something other people could understand and enjoy. In many ways, writing is like solving a giant jigsaw puzzle, except that you're also drawing the picture and running the jigsaw at the same time that you're trying to put it back together.
In college, where I was originally studying to become a professor of Classical Greek (see how the third passion fits in there?), I studied creative writing, and spent a lot of time honing my craft. The energetic exchange of ideas among us young collegians is an experience I've never forgotten, and one that is difficult to reproduce in the "real" world outside the university.
Fast forward several years. I wrote a novel that I really like (during some slow years in my programming career). It's a fun, fast-paced suspense story (a kidnapping caper). As the indie publishing world grew up around me, I decided to jump in headfirst, and I published Sierra Girls on Smashwords and Amazon. It has received many nice reviews, and I'm quite pleased with how it turned out.
