I'm still amazed the fight seems to be "everyone works from home" or "everyone works from the office".
I've been fairly productive since we all started full-time from home in March. However I prefer working at the office. As time has gone on I've found myself losing routine. Either working sporadically through the day or longer hours in general.
Being somewhere does a better job for me of time-boxing work.
That being said, I also have my work and personal machine in the same room. So now I'm spending most of my time in one room! I'm working to rectify that situation.
