I was wrong, it's not complete bullshit. It may or may not be <i>mostly</i> bullshit, but it's at least <i>some</i> bullshit. It's title itself is bullshit and reeks of charlatanism. Come on, "the master key", as if there is some master key that will "unlock your true potential, and make you the true master of your fate, and blah blah blah..." just like all self-help type of crap peddled by snake oil people.
In the search for wisdom, you will probably agree, you end up sorting through a lot of such crap. The foreword and introduction are more of the same. But the very first sentence of chapter one is actually wise: "much gathers more... and loss leads to greater loss". That's a very good thought right there, proving that the book is less than 100% bullshit.
