but I'm sure it helps that writing isn't my full time job
Yeah, even though I spend as much time as a "full time" Steemian would do, I don't consider myself to be a full time Steemian as I'm still a freelancer and don't rely on my rewards as my main source of income. However, I spend literally all my time online, so Steemit is obviously easy to reach at any given second.
Haha it is for me as well, but being an engineer I get to take some breaks and crunch some numbers. Makes it easier when I don't need to be creative all the time and can switch which part of the brain I'm using, but noticed I still need to take breaks to avoid and recover from burnout.
