Mate, I have read your whole journal and I see you have been doing great on opening and keeping conversations going. I believe that you are just lacking kino escalation (which works wonders).
Next time, try to start kino smoothly and keeping progress. Make you movings without the girl realising what you are up to. If you are able to do this well (fast and smooth) you will make k and f closes in a daily basis.
I was there. I was able to open sets easily after some time (which is unbelievably hard in Brazil, where hot girls are usually totally stuck up), but ended up falling into friend zone.
It became very easy to build attraction, but I could not escalate. It was even harder then before studying pick up (and I have always been good with women. Got drunk, lots of approaches, lots of rejection, but always one close with direct game).
When I started escalation, it all changed like magic. Now I can escalate smoothly and fastly, and I've had almost every girl I've had home to bed.
Try that next time and surprise yourself. Please keep us updated!
