Congrats on starting so early. As some smart dude has said "If you can imagine it, you can achieve it." Save hard when you are young and buy your freedom to chase your dreams.
One person I know started making stuff and posting pictures of it on Facebook. Somebody who saw the pictures wanted a sample of it and the journey that started here is now a very good home-based business! Once you gain some foothold, you may want to ask for some space in a mom-and-pop grocery store where you can test the market.
Best of luck!
