I truly appreciate your ringing endorsement, Droogs, but I actually somewhat disagree with your assertion that my book should be the first book on any aspiring woodworker's list. Not all aspiring woodworker's develop a real passion or long lasting interest in the knowledge, skills and proficiency required to be good or successful, so the subject of timber technology could rather pass them by.
But outside the casual (disinterested?) wood hacker, or short-term woodworker that soon gives up, there are those who really want to know how to properly handle wood to avoid failures and disappointment in their constructions, and I'd like to think there's a role for my book for those people, with the subject matter having equal relevance to machine woodworkers, hand tool woodworker's, and mixed machine/hand tool woodworkers.
Every sale of my book results in income for me, of which I heartily approve of course, so from a selfish point of view the more sales the better. But I do think it's important that the book is purchased for the right reasons, e.g., the buyer needs it to genuinely develop their woodworking knowledge and skills, and has a genuine interest or need to improve their understanding of wood science. Slainte.
