Piecing together from the rent cost post and this that your parents must do well. No problem in that. That said, I do think there is good value and character building in throwing in a day's work but you are still young ans likely finishing school.
Tbh, if I hit the lottery I would certainly not be doing the 9-5 gig but would still do work.
In the case I didn't mention it, I actually live with my parents in a suburban house. They would have a hard time paying for a separate flat for me (especially in or around Paris). Still yeah, I'm aware of the fact I'm clearly more fortunate than most people.
I was actually thinking about giving private lessons to high schoolers one of these days. I agree that I need to earn my own money at this point, even if only a symbolic amount.
