Something I have seen a lot of beginner guys and even many intermediates get wrong is handling things when a girl starts to qualify herself.
There are many ways women will qualify themselves, but one of the ways a woman might do it is to excitedly tell you about an interest or quality of hers she thinks might interest you.
For example, she finds out that you travel and she starts talking about how she really loves travel, then spools off a list of places she's been to. Or she tells you she hasn't traveled much but she thinks travel is so interesting and tells you some place she really wants to go to.
A lot of beginners will treat this like "okay, she is trying to build commonalities with me; I should vibe with her on that."
There is some element of that in there, but what she is really doing here is qualifying herself.
And when a woman qualifies herself, you have to reward.
