Absolutely. It really feels like the book has a lot of useful information, but after the first couple of chapters it becomes almost impenetrable. (And I am used to reading technical papers!)
If you've never done Enterprise sales/mktg for a new product before, you will hear practically every objection written there.
It's sad that the writing is too heavy for people. It's well worth the read.
But deep down, I'm looking for step by step instructions. Standing on the shoulders of giants, someone will eventually write it.
