I agree with this. Why?
"Doing the homework" is doubly important when the book / theme involved is any kind of a non-fiction, how-to, or similar book, like the one you critiqued about extra income for seniors. Those will affect the lives of countless people the author doesn't even know, who trust what they read.
The bad publishing (upside down, backwards, pages falling out) would be an immediate turn off to me, as it was to you. I doubt I'd finish reading one of those, either.
As for bad/no editing,I've commented to you more than once about the way a former English teacher and I would trade stories about the atrocious grammar, punctuation, etc. we each have found in emails, memos, etc. in the past, even while we were on the job together as contractor computer programmer / analysts. There was so much of it, the tales we shared never stopped.
And as for wanting a piece to be the best it can be before it's presented to the world as a finished product, that's exactly why I haven't done anything with the book yet. There are still a couple points about it I'm wrestling with, and why I'm up to the 8th draft overall. So I can FULLY understand why some famous authors admit to taking years to get their books published. That ache to be a writer also means caring enough about the quality of one's work to want / need the peace of mind of knowing we've done the best we cound, and being comfortable with the impressions, both first and lasting, that our work will leave with those who read it. This one is a no brainer.
Finally, the basic thought you express here is also very true, and important: that writing begins in the heart, and grows until the ache it creates becomes one that must be satisfied. I couldn't have said it better myself. I felt that starting back in 1980. Been there, done that.
Thanks for putting all this into words so well, and so accurately.
