And basically feel like i made a mistake. I trusted a friend. I created a webpage, and spent more money advertising. I'm a fool. But now i have people interested but not making the move, so I'm torn.

Should i keep trying to sell a business idea, or should I close down my page and just take the loss?

Supposedly people are making hundreds of thousands. I'm missing something, i haven't made a dime. Spent money i can't get back. And I'm suffering because of it.
