I worked from home for about three years. At one point I had an entirely separate desk and computer for work, adjacent to my personal computer and desk. This is legally required for tax purposes, but it's also the best work/life balance I could find and still maintain focus. If I'm in the work chair on the work computer, I'm working.
That's another thing -- having a chair makes a huge difference. I'd been sitting on a water jug at my desk for the last few months and recently got a chair -- what a difference! (I wish I was joking/trolling)
