I only read the preface and a little more of the book Art of Deception by Kevin D. Mitnick so far but it already surpassed my expectations - and I would say I had pretty high expectations.

It's a book from the "world's most celebrated hacker" and "delivers the lowdown on today's most serious security weakness - human nature" (quoted the back of the book).

So it's a book about social engineering. And I believe knowing how social engineering works can be useful in all kind of ways in life since you can also apply in for non-malicious purposes; the most obvious one being to defend against social engineers.
