If you have old clothes / shoes / other stuff that you don't wear or don't fit you anymore, you could always sell them on something like Vinted or Depop assuming you have the means to post something or drop something off at a locker!

On the sketchier side my friend used those survey apps non-stop for like a week and ended up making about £70, it's probably not good advice but it sure works if you're really in a tight spot

depending on the situation, you could totally do art commissions online. like set up a paypal account etc. it may take a while and i havent started them myself personally, but its an option!
bestest of luck

you could start content creation, like a youtube account or a tiktok account!

If you like doing arts and crafts you could maybe try making stuff and selling it at a market (if that's available to you) near where you live? I know some people who do stuff like crocheting, pottery, and printmaking who make money from selling their stuff at farmers markets and that kind of thing
Best of luck! :>

Okay so
You need venture capital, something you save up, maybe over birthdays and such.
Then, second-hand marketplaces are your best friend. You look at things you can pair up to bundles, me personally I did retro gaming consoles and games. You bundle something up (I used to do console + 2-3 games, restore it all, clean it) and then sell it.
Tip: Put the price at around 150% of what you spent, so if you spent 100 dollars total you put the price at 150, and expect it to drop to 130 or 125 through negotiations.
Spin this around a couple times, it compounds. It does take time though

YESSS, honestly i feel you because my mom is already pushing me to get a job so i can pay rent/phone bills/and my gas money ( ;´ - `;)
but i hope the best for you and hope you can find a way to make money, i’ll be cheering for you!!٩(ˊᗜˋ*)و

I'm in the same situation! But if you get consent from your parents, you can try Facebook Marketplace. I would say, for safety reasons, maybe meet at a middle point so they don't know where you live.
<3 I 100% get you, though it's so annoying. Where I live, they don't hire teens either :(
