One other important thing is that there are also things that are missing from a book like this that might matter in terms of why a particular action worked. (At a particular point in time) Because they might appear to be sleezy (even if they aren't) and someone might not want to mention them for wide review or reading or have them known. So honestly you never really know the full story and without the full story it's hard to nail down exact steps and honestly you can't do that anyway (for example you can't control luck). [1]
[1] Not a great example but let's take an actress writing a book on how she got her first gig in Hollywood but she fails to mention how the director had the hots for her and what she might have done to lead him on into thinking she would sleep with him. Instead she just talks about things she can and people reading give that greater weight.
This is in stark contrast with John Doerr’s recent book, Measure What Matters, which is only examples of implementation.
