I would love to see some of your background, ie. what made you competent to write such book. Some info regarding content would be also a nice to have - I know, what your book covers, but how is it structured? How many pages it has?
The paperback is ~120 pages at 6x9. The ebook is ~43 pages. My background I just linked here - https://news.ycombinator.com/item?id=6399538, but basically the gist is I quit my job a bit over 2 years ago with very little income, and I'm making a nice living on it now.
To make my point more clear - my intention was not criticizing you, or doubting in your competences - from potential buyers point of view, if would be nice to have this informations somewhere on landing page. I did check your "background" before writing above comment and in my opinion you could add some more info, that would make you more trustworthy for visitors from outside of HN.
I've worked on setting it up with Amazon match, but I'm honestly not sure how that works. If you can't figure it out shoot me an email - clarky07[at]gmail and i'll help you through it.
