Did freelance marketing in high school and currently writing a sponsored newsletter. Approached both out of genuine curiosity. I quit the freelance marketing gig once I started college (lost a big client at that point anyways), but I still write the newsletter if I finish my dsa homework lol. Wouldn't really consider either to be businesses, moreso side hustles I was interested in.
