Hey.... chin up... just because this idea didn't work out, doesn't mean that something else won't. All you need to do is find a product that people NEED that isn't readily available in your area, and then supply that product. Sometimes it could be as simple as breeding mealworms or superworms or ??? Or it could be something that no one else has thought of .... YET!
Don't give up on owning your own business... and don't you EVER let people tell you that you are too young!! There are kids FAR younger than you who have created their own businesses and are doing well!
