This is another retarded faux-revelation thread.
When I walked into a bar and sat down next to a girl one summer night in college, I thought to myself, "I can definitely run a smooth game and get on this TONIGHT". This type of state oriented self belief is the driving force that keeps guys determined after being brushed off, ****blocked by her girlfriends, her being hit on by other guys, to be the guy at the end of the night that waits out the bull**** and gets her home. But in this case I ended up going back to her place at 8:30 at night.
So I didn't really read your post, but the title is just not correct in any way. You have to have that belief that you can get laid, sometimes that's all there is between you calling it a night or waiting 15 more minutes through some small talk for that "spark" to happen.
Also one of my best lays, a ONS with a knockout british bombshell on vacation, began with me walking up, smiling, and confidently saying, Hey whats your name? Sounds simple but to say that with unwavering confidence and warmth that makes the person want to get to know you better, took me a long time to iron out. When we were relaxing on beach chairs at 5am the next morning after an hour of crazy beach sex, she told me that what she liked most about me was my confidence in going right up to her and asking her name.
