Is this a challenge for privileged "middle class" people? Anyone who is actually struggling for money lives like this all the time.

I definitely have seen this trend around tiktok, reddit and YouTube. I haven’t tried it but I feel like if I tried it I would just postpone my nonessential expenses and then go back to my normal mode of operating.

Hmm...

I think I use YNAB to allow myself nice things while knowing I'm saving. I guess it's because I've got a saver mentality instead of a spender mentality. So I don't think the challenge would be useful to me...

YNAB gives me permission to eat out with coworkers when they invite me on Friday... Before YNAB I would feel bad not to eat a packed lunch.

I'm just not someone who buys unnecessary things on a regular basis. (I lean more towards splurging on outdoor gear once or twice a year.)

I like budgeting because it meant I didn't feel guilty buying two board games on FB marketplace this month even if I knew it meant postponing a purchase of an epilator until a future month.

I've tracked all my spending since I first moved out of my parents place for university... I think I would struggle not to. My anxiety loves loves loves worrying about money. Forget the fact that I could have no income for six months and live my usual life...
