Best Way To Make Money As A Kid (not a child goat)

When I think of economics I think about my job as a kid that mows lawns (or low mawns as my sister would say) in my neighborhood. I usually earn around $40 per lawn, except at my house where I get $5 for the whole lawn. Sometimes I walk around the neighborhood and stick this flyer I made in doors. My dad bought me my lawnmower and I had to pay off $400 dollars by using said lawnmower. It took 2 months but I finally paid my debt and I could keep all of it, half to my bank account and half to my wallet. What is your job (if you have one)?
