Glad to meet you. I joined Steemit back in August, then took a break in October and just got back on last week (I have a re-introduction post on what I've been doing that whole time). I'm a full-time freelance writer and author of two novels (and working on my third), and have been working from home solely online full-time since 2008, and part-time since 2002. I do, indeed, often spend 12 or more hours a day on the computer. There are other things I might like to do, but until my crypto investments start paying me a full-time income (or a giant fortune), or my book royalties get to a full-time income point, I have to be here in front of the screen, as I am the sole source of income for my household. It's not so bad, though. It's better than being out in the world, working for "the man." I hated that, back in the day, when I was a teacher, and then a background investigator. I'm meant to work for myself. I don't do well as an employee. Lol! Glad you've joined us. :)
