I wonder why this is being downvoted.

The War of Art is undoubtedly a self-help book, and so is How to Make Friends and Influence people. Both contain little more than trivial platitudes IMO. I have not read the other books, but from the abstracts it looks like several more can be considered self-help books.

I was hoping for hands-on books like "The Art of Electronics" by Horowitz & Hill or similar.
