It is understandable that you want to convey some sense of authority, i.e. you being the domain expert. I could be wrong but that will not sell it as much as highlighting the PAINS people face (provided they do).
I'd much rather sell them on pains - something that resonates deeply with them - like "Did you ever try to implement Stripe integration and lost sales as a result of some bug?"
If you do your market research diligently, you won't have to 'invent' those pains/scenarios - people will tell you. As Ogilvy said initial customer research is a must for good copywriting.
It is easy to focus on what YOU know, what YOU experienced, how it helped YOU. But to take it a step further you need to talk to other people.
That's what I mean: http://www.smashingmagazine.com/2012/05/18/quick-course-on-e...
Also, refer to Joanna @ Copy Hackers - she's got some great books on the subject.
Hope it helps.
I rewrote the whole first paragraph and added some bullet points. I promise I'll stop bugging you now :)
Don't confuse that with a market test - i.e. even if people say they would buy the book - it's easy to trick yourself into thinking like that.
Selling infoproducts is a big topic, there are so many important things to it, such as building a subscribers base, all te inbound marketing in form of blogging/guest blogging, timing your launch, discounts to loyal subscribers etc.
I'd recommend studying successful use cases such as Nathan Barry, Jim Gay, Brennan Dunn, 30x500 course alumni in general - they seem to have nailed it.
