Reading up content here, many times, still trying to get through, I am not where I should be, but I am slowly going there.

I always had a gripe with STFU. I never understood. In my own experience talking about things that I am passionate about always helped me with women. My game is "talking" game. I am still trying to build my confidence to the fullest, I am still trying to build who I should be etc, but talking was my one power that always helped out. So understanding the concept was really difficult for me.

Until I met people from USA. To clarify, I am from a small country in europe that people from USA never visit, you never meet them here. But I did meet a couple while I was on vacation in mainland Europe.
The stereotypical american couple, two fat people, loud, obnoxious and OMG never shutting up, NEVER. Like, they could not last 15 seconds in silence. Seriously,
I know this is a shit quality post compared to what else is here, focusing on one aspect without giving too much valuable info so here's some.

Learn to enjoy the "awkward pause" learn to enjoy the silence at moments. Don't try to fill every single second with loud noises. This is a general rule in life, don't be an obnoxious attention seeker that cannot last a single second without talking or getting people's attention.

And to flirting. USE the damn silence. When you have an awkward pause, that's the moment when you make deep eye contact, look at her eyes, lips. During those silent moments is when your non-verbal communication should be at its peak. Have the next subject to discuss ready, but USE and ENJOY the silent pause. Then, after you made that target, she will either break the pause, or she will also enjoy it.
Use the pause for your non-verbal "push" and then, break it with a verbal pull.

Also, given how retarded some of you here are, I can predict right now that after 3 minutes of awkward pause, you break it by saying "I gotta go take a shit"
