The sample chapter doesn’t really give me much confidence that I will learn anything new from _your_ mistakes.

Suggestion: make some more chapters free so potential readers can better gauge how useful it will be.

Thanks for the tip! The book describes the approach that helps prevent my mistakes, and in each "step," I add several warnings and information sections about what to do and what not. I will try to think of how to add a better demo.
