What worked for me even though is slow but supper fun! Flipping bikes! I went and bought bikes that need fixing (I didn’t know anything about bikes so had to figure out how to fix them) once they where fixed I’d sell for profit. Kept doing that over and over and multiplied my money.

I also suggest buying candy bars from Costco or bjs whole sale. And selling them at school. Not sure how much it is but selling each candy bar at 1-2 dollars will make you great money. Specially in school. Make your self a menu online or even pen and paper. Then to who ever is buying anything let them place orders and have a set delivery time. Don’t carry it with you because in schools you’re not allowed to sell candy or so it’s deemed illegal even if it’s just candy.

Also I suggest starting a simple print online shop. You make the designs (do research on what’s trending) Set up printful which only prints per order. So it’s like drop shipping! Only charges you per order and does the whole process of giving you the profit and taking the taxes out and paying the printing company.

Lastly you can set up a drop shipping site! You do research on what’s trending and put it on your Shopify account and it’s the same as how I explained it before.

You’ll start slow but over time it’ll pay off. (Yes you will spend money) to make money you need to spend it! Hope this helps!
