I have activities at the end of the day which require me to quit. I play pickleball with friends, coach my kids in baseball, dinner with my family.
I'd find things to do. Even in 2020, you can still get together with friends, even at a distance. Ride bikes, hike, walk to get take-out.
Set a calendar notice to "GET OUT" of your office to help remind you. Or you can borrow my 3 year old who will ask you to play "strong guy" with him until you give in.
