I have spent most of my working life as an engineer of one sort or another (broadcast engineer, software engineer) and people who know that side of me are surprised when they learn about the writing side. I like science and engineering because I like to know how things work, and I like the arts because I like to know how people work.
It took me 50 years to graduate from college, because I kept getting distracted by life, but I finally earned a BA and MS in Computer Science. Having accomplished that, I started writing a novel, which turned into a trilogy. I don't know why I needed that degree to write, at last, the book that I always knew was in me trying to get out. Maybe I just needed to be old enough.
