The Value of a Book

When i first was launching it, i had just tweeded, would people pay ten dollars for this? And i had a couple people say, i would pay more for this. But since then, it's actually gone up to a hundred dollars. I think in the case of your book, what actually happened was people bought it, and for the price that they paid, they thought it was extremely good and valuable. So as soon as i had that social proof, there's no reason why it couldn't even be 200 dollars or more than that. The things that you pay more for, you automatically psychologically attribute more value to them.
