Great list of books to read, and list of those to listen to. Spot on, IMO.
Not trying to nitpick here, but I found a bit of a negative tone, a "doom and gloom make the reader afraid" style to the writing. And while I agree with a lot of what he was trying to say (again, IMO) I feel if you're going to point out the difference between "techniques" and "principles", you should do exactly that. I don't think he did. "Escape" which is important as anything discussed, isn't a principle, it's a strategy. But there are principles involved in escaping.
