I understand about the spill over effect. I did not have much of a problem with that since it was in the last years of my working life and my children were on their own. I can understand that having a family around would be more complicated.
When I started working from home, I would have breakfast with my wife, kiss her good-bye, and walk the few steps to the office. I’d “come home” for lunch, work the afternoon and then we would make dinner together. Once the routine was down it was easy to keep the two lives separate — when I commuted I was usually out of the house 12 hours a day! I admit that I would return to my home office too often to put in those extra hours — I too loved my job.
I am enjoying retirement (but not the limitations of living on a fixed income in a country where every day the cost of everything seems to be rising like rockets into outer space! My best advice: save twice as much as you think you will need when you retire!!) I still go to my office every day — I am working on a book (and the Medium essays, and about a dozen other things ) so retirement really doesn’t feel much different than the last few years of working from home. Well, not true. It feels great to set my own deadlines.
