I never thought I'd handle WFH well. When job-hunting, I'd always ignore fully remote jobs. It sounded totally depressing and demotivating to sit at home and interact with my coworkers virtually. I also always valued the office perks.
During the first few months, it felt like WFH stripped out all the non-work aspects of my job. At Google those perks were substantial, and it put the work itself in full focus.
But you know what? I like it now. I'm able to put in more focused work between 9 and 6 because I can take real breaks. There's less BS intruding on my life. In the office, your breaks feel more limited to 1) walking to grab a snack in the kitchen, 2) scrolling through something at your desk, or 3) going all the way outside to take a walk. 2/3 of these make you look like a slacker when you do them too much, so I always ended up doing a lot of "pretending to work" breaks to refresh my mind. That said, nobody ever had a problem with my performance.
Now I can pop out and walk around the block in 10 minutes, or wander into my back yard. I can do manual chores and intersperse them with knowledge work to give myself a break. I also don't have to commute for 2 hours each day. This means I have more time and willpower and actually get more done. I actually measure every minute of focused work, which is how I know.
