When I moved, I gave up a 7km (4 miles) bike commute along a river and switched to WFH. Definitely missed that.

I also feel disconnected from work when WFH, like I don't care about the company at all. The obvious problem is that it made me think the time spent working was quite a waste.

I didn't take as many and as socialable breaks.

When I was unproductive, I felt internal psychological pressure to work longer. Now in-office, I clock my hours and am free.
