As a freelance writer, I charge by the page and say something like "I typically get it back to you within a week." In reality, I usually get it back a lot quicker than that but saying that gives me latitude for being too sick to work unexpectedly sometimes for a few days.
Charging by the page means it's my problem, not yours, if I can't focus and have to read it three times and it takes me longer than usual. Sometimes, I can do it efficiently and sometimes I can't.
I have zero desire to have any kind of "job" ever again. My life works vastly better as a freelancer who can do the work whenever the hell I manage to get my act together for the day without punching a clock.
This is literally worth millions of dollars in medical care not being required that normally would be for someone like me.
I'm dirt poor. I hate it so fucking much and wish it weren't true.
It's also the version of my reality where unicorns fart rainbows compared to what I'm supposed to be enduring.
