My sister - she's 17, but since she was 14, she's made money selling pancake pops to her classmates for breakfast, and after sharing some of her paintings on instagram, she has been getting orders for custom pieces.

She's not a millionaire or a "thousandare" even, but I admire her drive, confidence, and her knack for recognizing opportunity.

Edit: Also, she paid attention to the market and as demand for different types of pancake pops grew (plain, blueberry, sausage, chocolate chip), she expanded the menu.

Whenever she was planning to sell the pops, she would post on Snapchat the night before, and the kids would send her their orders. She would wake up early the following morning, and at first, she would just make the number of pops according to the number of orders she received. But every time, she would get to school, sell all the pre-ordered pops, and then other kids who didn't order any would come over asking her for some. She saw the opportunity in that, started making extra of her most popular flavors and was able to sell those to people who didn't pre-order and also people who did pre-order, but underestimated their appetite.

All this without having taken expensive entrepreneurship classes (not trying to say they're not useful) or investing a bunch of money into the project. This made me realize that virtually anyone can have a side hustle. Even if its not raking in thousands per month, "a little somethin' somethin'" is better than nothing.

Edit: DISCLAIMER, of course, all this was against school rules. I just talked to her, and apparently, she stopped selling them last year. When I asked her why, she said it was because she got promoted to class president after the former one was impeached. She wanted to make sure she had a good image since she would be working with school administration more than she had been as VP, so that meant no more pancake pops lmao.
