“Once you become educated in the way of women, it’s natural to become a bit jaded. Over time, this passes, as I’ve discussed—you must let go. If you don’t, you’ll just end up a miserable old hack.
But learning the true nature of how male and female dynamics works does something else. You can get the women you always lusted and desired for. You can have sex with them, and you can even keep them around in a happy and fulfilling relationship. But it all comes with a trade off. Things will be different than the fantasy world that you grew up in.” 
The reason behind it is quite simple, Kyle hit on something that I’ve thought a lot about, especially in periods of my life when I run very active game. One of the habits I developed early was to keep rather comprehensive notes during these periods, not only to keep track of the different girls, but also because I think they are very valuable as a tool to help me improve my game. If something blows up in my face, I can go back and review, see where I went wrong and then take steps to avoid that happening again.
Let’s be fair, you can over-game, under-game, over-comfort, under-comfort, be too entertaining, not entertaining enough, too sexual or too non-sexual, horny instead of sexual and many other things. Most of these are dials that have to be adjusted based on the girl, the context, the culture and many other things. If one of my stories, or a sequence of my anecdotes is more effective at achieving my goal, I want to be able to put that into a pattern, to increase my efficiency.
So, I like my notes for this reason, they are my impressions shortly after the meeting, significant moments are recorded and I can go back, look at the variables, make my adjustments and improve. This makes me more efficient and gets me more results, however it also removes some of the organic, natural parts of the interaction. It’s a bit like playing Starcraft for fun vs. Starcraft as a pro gamer, sure the pro gamer is better at the game, but it’s all automated, there are few if any surprises in it. However, sometimes you get hit with a surprise.
What Kyle touched on, but didn’t make explicit was the trade-off between two sets of things, set 1 are the principles that make up Red Pill theory, hypergamy, solipsism, AF/BF, communication differences, the adventure bubble, escalation and such things. The second set are the dynamic variables that to some extent are both objective and subjective. These are shared among all girls, but the dials are set to varying levels, a good example would be the ovulatory shift, a girl who is in her proliferative phase can be escalated faster than a girl who is not. If she’s also got 3 drinks in her, has been without sex for a month, is in a foreign country and is under 25, she can be escalated even faster.
Starcraft has rules, and an optimal strategy, the Red Pill has principles and heuristics.
