I've recently taken a leave of absence from my day job and have been focusing on my writing and editing full time.
Over the last couple of weeks, I've learned a few things about myself. First, I am much more productive if I get a half hour power nap after lunch.
Second, the human body was never meant to sit and type for eight hours.
And third, I've learned that I'm a "task person" rather than a "time person."
