How do I find a job at 15?

Hi, I've heard about a 6.5 month school cruise and I'd love to do it. The only problem is that it costs a bit more than 20k. Well, I don't really want to pressure my mum for that amount of money, so I'm looking for a few jobs now :). Even if I don't make it, I'm willing to have the experience and learn to become a bit more independent.

Now the big question… What kind of work can I do at 15 in the Darmstadt-Dieburg area? For example, I've already been tutoring for half a year. I'd also be willing to do things like waitressing. I'm open to a lot of things.

Have a nice day 🙂

Greetings ^^
