I had a few jobs when I was that age.
The lesson I learned from those jobs is that hard work doesn’t necessarily result in a worthwhile reward. And often just not worth bothering with in the first place.
You experiences may vary.
On the flip side, I effectively worked for my cousin on a small holding. For free*, mainly because I liked driving tractors. That was great. To be fair, there was some remuneration involved as I had a flock of sheep and geese that both went to market. I also got to bury a dead cow, which didn’t seem odd at the time.
*Technically I guess I was paid with Tea and Bacon sandwiches.
