Haha it’s so ridiculous that these articles never take into consideration that people in the office don’t have a lot of productive time.
I had the same, I would have a somewhat easy first hour, then spend 2 to 3 hours really focusing and then I’d basically be done for the day and would spend some time idling after lunch until I deemed it was an appropriate time to leave and “work some more from home”.
My best year billability wise was the first year of the covid lockdowns, I managed to generate something like 25% more just because of being able to work from home and cutting back on the travel time to customers and being able to multi-task occasionally when I had a quiet day for a customer. I’m glad I live in the Netherlands, hybrid/remote working seems like it’ll remain over here at least.
They also very much had the advantage of knowing their terrain and both Hitler and Napoleon got cocky and kept going during winter time without being prepared for it. Hitler especially was actually making good progress until winter hit so you could almost even say that Russia took a calculated risk (even though I think it’s more of a “got lucky” situation).
