I've learned that I'd genuinely, genuinely rather earn on my back or my knees than do office work. I mean that more wholeheartedly than I can say.
God yes 100%. I had a really good job before entering sex work, was on a good career progression track, worked with some great people, was using my skills and experience to improve productivity and working conditions for my direct reports.
Yet even as irritating as this job can get with time wasters, I would 100% not ever go back to the kind of job where I have to bite my tongue and be diplomatic with dickhead colleagues. And I'm pretty easy-going generally, I'm not hard to get on with. But at least when I get a dickhead punter, I can grit my teeth through the booking in the sure and certain knowledge that a) I've just taken £120 off him so I can put up with his bullshit for an hour, and b) as soon as he's out the door I can just save him as "Boring bastard don't see again". Not something you can do with a colleague, sadly.
If I leave sex work I might go back to the same industry but I'd be contracting. I wouldn't be a salaried employee for anyone else again. I'd rather know that my earnings are directly related to how hard I work and how good at the job I am.
