I don't remember exactly. I think it wasn't very many. I was probably ready with the first one. I just went with the blip page and accepted that that was it. I forget whether they emphasize this in the book or in Alex's posts, but basically, if you see the blip or see the book softly, and at any rate if you aren't preoccupied with the evils of your boss or how your company is being subject to a hostile takeover or something, then you're set to go!
