I used to have a 10 minute walk to work, and it was great. I'd take 1-2 days WFH a month still because there was some work that simply needed no interruptions/distractions.

Now I have a 60-75 minute commute over underground, and I'm not looking forward to the return to the office. There's definitely aspects of working where I long for the office, but others where I'm glad for the solitude.

If we have to return 5 days a week I'll probably have to move and pay much more or have a tiny living space.

I value my time more than my comfort so am accepting of this, but it still frustrates me after living the afore mentioned dream.

I'd also note that I regularly start work an hour or two early since working from home - with >2hrs of commuting slashed from my day, if I get a good thought at breakfast why not bash it out?

When you're facing 12hrs as a baseline for your working day it's much less appealing to contribute outside that time.
