I just keep the 'busy' hours for other people. Thankfully WFH has made it easy. Basically 11AM-7PM are for other people to interrupt me, and for calls. I stay only half-engaged with chats and emails so it doesn't cost in me my cognitive budget and I get a lot of stuff done within the household. Either 7AM-11AM or 7PM-11PM, depending on circumstances, I do work. You know, the 15 minutes of real actual work mentioned in Office space. This is when other people are away and I get to focus. Thankfully my company culture is good and nature of my job allows me to only sit and mash keyboard couple hours a week or so, rest is thinking, or light research.
Overall, I don't engage with $JOB more than 8 hours on any given day and never on a weekend. It works for me, and my boss nor team have complained so far. I'm not sure how long the party will last, though.
This is basically what I do too. It works fairly well, if I have an open day.
Setting aside “helping” time and “focus” time is extremely useful if you can avoid meetings during your focus times; although it is also difficult for me to focus when I have something happening soon (meetings at end of focus time, etc)
