Not cassepipe, but also currently living on (less than) minimum wage, in an expensive part of Paris, France. I'm cooking, coding, reading, watching youtube. This year has been "great" for me. Of course I would have liked more comfort, some foods I can't affort but, but I've got a good bed, a good chair, an excellent desk, good cooking knives, an ereader with a practically infinite supply of free books, computers and hard drives (hidden) everywhere in my 20m². I write the kind of code I like to write, I'm not accountable to anyone. (not anonymous you can try to name search me to cross check)
I estimate I'd need about 30k€/y to be able to not skip on anything I'd want to do. (usual disclaimers apply: young-ish single man living alone, never had health issues, with no desire to live in any other way, etc)
