Entrepreneur and author James Altucher recently offered to give money back to anybody that proved they bought his book and read it all the way through in the first 3 months after the release. When asked why he didn’t just give it out for free, he gave a great answer:
I’ve given EXTRA things for free in many cases. But you always want a paying relationship with the customer. Or, as Porter Stansberrry has said to me, “your free audience will kill you.” How do they kill you? They always expect good work for free. They set the bar higher and higher. And they feel comfortable dictating what free things they should get from you. I don’t know why they do this. It must be some biological thing. But it happens.
