I agree when it's one or two days here and there from home - when I used to work one day from home, I would do everything in my power to get as much as possible wrapped up by Tuesday night, and not schedule any meetings on Wednesdays so that I could have a light day of just checking emails and addressing anything that came up.
Once I transitioned to full-time working from home, I still had to get my full-time job done. Like I said above, yesterday for example, I was online working from 6:12am to about 7:30pm, with a few 5-10 minute breaks here and there to use to bathroom, check in on Disboards lol, and throw a Costco tray of alfredo pasta into the oven. When you work full time from home, there isn't time for you to be goofing off - the work still needs to be done and you are still accountable for it. I routinely work over 50 hours a week - legit working - and during our busy season, up to 70. All from home except for Wednesdays when I meet my team in an office. My whole team agrees that we work smarter and harder at home because we know that if we get done early, we can address the dishes, laundry, etc instead of wasting time sitting at a desk in an office until 5pm, but in reality, we all pretty much have too much work to do to get "off" much before 5 anyway.
