I know it's insane. Not looking forward to going back, currently pegged for January.
Thing I'm gonna miss the most is mornings... Me and my kid sleep in till 730/8, she watches 15mins of cartoons or flips thru a book will I wash up and get dressed, then we do her routine, then eat breakfast, out the door to daycare for 845, me back to work on my computer for 9 or so and ready for the day.
Versus... Me getting up at 620 hoping she sleeps in, only to rush to get her ready in 20min and out the door to drop her off for 730 to sit in traffic for an hour hoping I make it for 845/9. Just sucks.
Same with bed time. I've picked up my daughter every day for the last year or so, nice routine she gets so excited to see me, pick her up at 430/5. Instead... Most nights I'll be sitting in traffic till 630 with barely enough time to get home to see her before bedtime... Let alone eating dinner together, and my wife will be in a bad mood because she's been doing parental duty alone for 90mins.
Sucks.
I think If you're young and single the incentives to go into the office are really good. It'll be good for your career , face time with the upper management will be very good and the social life around work will help you move up faster than someone who is remote and not going to social events or beers after work.
