I spent fifteen years as a QA Engineer. I was good at it. I enjoyed it but I had to move out of video games because they didn't pay that well. Now, I'm a writer and it certainly doesn't pay that well and it is hard work. I love it. Don't get me wrong. You have to love being a writer. Otherwise, it wouldn't be worth it.
Part of me, the QA Engineer, wants to go back to testing video games. Or, working more regularly for a video game company in general as a writer. I know why this is. I'm looking at the past through rose-tinted glasses, remembering only the good and forgetting the bad (long hours, early mornings, commutes). That doesn't stop the nostalgia though.
