I've been WFH since the mid 80s. For me, this had been a goal since I first heard of the concept of WFH back in the mid 70's.

I've never really though of it as anything but a positive. I don't have to drive to work. I can take a break when I want and start late and work late (or early) if I want.

I code so not getting interrupted or distracted and having a quiet place to work is a huge plus.

I've always been comfortable with solitude though. It's a lack of it that wears on me.
