How I understand it, first you must pass her physical attraction test. Not always; ugly creeps like Dennis Rodman and Seal don't apparently need it to snag hot women (or as Doc would put it, the physical attraction test applies "unless you play in a band"). The thing about being "light and funny" is Doc's way of saying that you need to, as you put it, "convey a cool personality". Being your own cool, funny, happy self.
But I'll admit that Doc Love's "System" is simply common sense written in a manner best for Doc Love himself, and that different guys need to formulate their own systems. This is what I myself seem to be doing now. I'm using Doc Love as a foundation, but tweaking and altering where experience teaches me.
Like I said, he still has problems, and although he may understand himself, it may take others a while to figure out what to do in real life. For instance.
After a bad experience I had (2nd page of Barbillus' post on Ganji games), I pretty much became a Doc Love disciple. I am able to see exactly how I screwed up in retrospect; but also that some things can only be explained by some girls dating you with no interest in staying with you, or whatever. Then there are girls who flirt with you even though, again, she wouldn't actually date you if you were the last man on earth.
After I got burned, I resolved only to ask for girls' phone numbers if they displayed "obvious signs of high interest", since I figured that these girls would be the most likely to get into an LTR with me. Unfortunately, I seemed to be getting only false alarms -- mainly insincere flirts (a.k.a. "attention wh0res"), and married/taken women who were totally comfortable around men. I couldn't figure out what I'm doing wrong. (Yeah, I'm a slow learner.) I asked a woman for advice (no, she's quite reliable) and she told me that my big problem was that girls with high IL aren't necessarily those who show high IL, and that a lot of girls are shy. Doc Love, on the other hand, doesn't believe in female shyness, but he did say that a guy should ask a girl for her # even if she doesn't appear to be interested, and my going "hardcore" was a serious miscalculation on my part. I got more dates when I asked for #s, and no dates when I didn't. Duh. I didn't get an LTR because either I didn't do the dates properly, or I lost interest in her.
Different girls react in different ways. Some giggle at every bloomin' thing you say which isn't totally dead serious. Others, on the other hand, can't be pleased; even if you say something that most girls would find hilarious, these particular ones are pretty much moribund in the humor department. As I see it, after they have a sufficient chance to analyze your personality, the ones who laugh a lot are probably more likely to have an IL above 50% in you than those who don't.
But I found that even this isn't totally accurate. I'm a chemistry lab TA this semester, and I'm grading papers for about 30 different girls (~70% female enrollment in the labs). It's a lab for me in a different way, although I'm not allowed to ask for #s until I'm no longer their TA. Strangely enough, those who laugh more at what I say are, again, NOT necessarily those with actual high IL. Just last Friday, the last lab before the Thanksgiving break, this serious 9 whom I thought couldn't care less about me since she didn't laugh nearly as much as the others actually seems very deeply interested after all, and her friend who is much more fun to play around with seemed to be simply a mere flirty party girl.
Another instance. There's a diner/bar I frequent every so often which has several different attractive waitresses. (Hooters quality, almost.) A couple of months ago, I chatted one up a gorgeous blonde taller than me; my buddies (including one girl) were claiming that she was into me, but when I asked for the #, she said that she couldn't because she was involved with someone else. Although my friends were highly impressed that I actually did that ("BGMan has ballz the size of Texas!") After a few weeks, she apparently asked one of my buddies where I have been for the last couple of weeks. I go in there on Thursdays, and she was there too on two occasions, but she hasn't gone up and talked to me, which led me to suspect that the guy who told me this was playing me for a fool. Duh. Girls are passive, she's wanting me to go up and talk to her, and she's very attractive anyway, which means I can't be a wuss. Although, a few of the OTHER waitresses there seem to display a strange warmth to me. (Kitty Kats Kompete)
Although HERE, Doc Love would say that because I asked for her # and she didn't give it, she has low interest.
