possibly stuff like working at a small gas station? or fast food works too, the average pay is usually something like 12 - 15 dollars (per hour) so that’s a decent amount for the usual stuff (clothing you may want, video games, etc)
especially since you won’t really have to pay stuff like bills yet, it’s a great way to make some early money

Mowing lawns and whatnot
