MinggBut rambling on and on about how awesome your job, house, school, family, car, money, etc. is not chill. Girls like to talk about themselves.
I can't agree more. I have a buddy who loves to yack about himself and after about 10 seconds I see a girls eyes start to wander around the room as she loses interest.
It's important to have something to talk about and discuss, but not ramble. If she asks what you do, don't give her a 5 minute lecture about how you got there and how you feel about it. Just give her the basics, say it's fun, you love it, you get to work with your hands, mind, whatever, and then move on.
Chicks dig a man who is interesting, but they really don't care much about what you have to discuss. Ask them questions, let them talk, show interest in them and their feelings and emotions and all that other shit.
Be supportive. That's your role in the relationship. Not to think or talk, but rather make suggestions. You're like a glorified walking cane with GPS. You guide the way a little, bring her balance, but decides where she wants to go. She's in control and it's about her. If other people happen to notice you with her, all the better. But it's you with her, not her with you. Remember that.
