Having (untreated) ADHD and spending 8 hours in an office is quite literally torture.
Even being able to only spend 2 hours max on actual work I was still seen as one of the more productive people in the company, ironically. But those 6 hours of either doing nothing or trying really hard to force your attention to come together are the actual work.
I'm very happy with remote work. I can actually find things to do in between that would definitely not be considered working that lets me spend more time being productive overall.
