Mariaxxx, I feel the same sometimes as what you described in your initial post.
I do escorting full-time and have no real hobby or anything I aspire to achieve on the side. I've done some civvy jobs in the past and I really wouldn't see myself doing it again, it's just so much hard work which isn't well rewarded and the idea of working for someone who can dictates what you can do/can't do is tiring.
I'm desperately trying to find some side projects I could start (especially when escorting isn't busy like now) but there is really nothing that I'm keen on or something I could see myself investing my time in (+ I don't have any real skills).
I also don't want to do escorting all my life but I'm quite money driven + I value my free time a lot so when I think about other jobs that have the same time/money ratio, let's be honest there are not many
