Hmn, as I thought pretty much utter crap.
Really it doesn't say that much other than for guys that they want to sleep with every girl (which isn't true - I don't really think - I have a lot of friends who are girls a lot of good ones who I really like, who I wouldn't sleep with).
Girls with the friend vs the interested ladder is sort of true I guess but I have been in places where you start off as friends and then lead into maybe a relationship (but that could be due to a girl wanting a relationship from the start and only pretending to be friends).
In the end it doesn't really say much, I think I've said more profound things about what a girl wants to see in a guy (read some of my past posts) and really this is just the tip of the iceberg (of a broad spectrum view of some of the individual issues).
Yes acting confident and funny will start you off in the 'like' ladder rather than being nice and pansy and ending up in the 'friends' ladder. But there's so so much left unsaid that this really says barely anything.
You have much to learn.
