This is part of why I prefer the opposite of the 4-day workweek trend. I typically do some work 6 or 7 days a week, but a workday might be only 2 or 3 hours, on some of those days. I don't feel like a workaholic, and am not doing 60-hour weeks or anything. I average maybe 30-35 hours depending on the week, but those hours are spread over more days. Outside of the occasional "in the zone" hacking session or paper deadline a handful of times a year, there's no way I can work 8 hours in a single day on a regular basis! But working on a problem for a few hours a day in a regular cadence, not long enough each day to get burned out, but frequently enough that I still remember what I'm doing – that I like.
