This took me awhile to adjust to as well. I had to set up an office space to keep it different. That worked ok but after a short period of time I found I enjoyed doing my work in different areas around our house to break it up. I think the biggest challenge has been not letting the days all blend together. So Friday my wife and I always go out to dinner and I do not turn on my work computer until Monday Morning. This way I enjoy a weekend if you will. It takes strong discipline to work where you live. I know quite a few during this pandemic that haven't faired to well working remotely.
Interesting now is companies are giving employees the option to work at home if they are willing to take a 10 to 20% pay cut.
