Well I have watched the short video (Thank goodness) and it hasn't inspired me one bit to be honest. It was dull, and didn't really show me anything 'revolutionary', which, as a newbie, thought I might be able to learn something. I fear the book would have me snoozing by chapter 2. 
And I think what Geoff means by sneaky is the fact you don't say it is your book in either of those quotes. You say it as if you are just recommending it. Therefore, sneaky.
