I know that ideas are worthless. I have some thoughts how to start small. The good thing about the concept is that the business can really grow. The very best part is that it can very easily grow by the word of mouth. I think I'm going to build a small business plan and start working on the project itself.

As for the books. I read a lot of them. But, I came with the concept while I was reading "Zero to One" in a subway train. At one moment I got like a recovery of sight. BOOM! I closed the book without intending to open it again.
