It's a miserable grind. Routine includes alarm, after a poor night of sleep, getting ready, commuting in, loud, bright offices where while you enjoy the convivial nature of joking and commiserating with colleagues, it's so distracting and noisy and visually distracting that you can't be productive technically.
Next you go home at 6, 630, sleepy, go to the gym or do your shopping, home, sleep, rinse repeat.
Suddenly six months has gone by. Then a year.
I cannot sympathize with the work from home complainers. You folks are like people who came across a lot of money, retired early and are depressed due to boredom.
If WFH is misery, is it possible it's the town you live in that's causing the misery?
