To answer answer your questions, my confidence shot through the roof. A friend and I started on this website this past fall semester.
Here's the thing, I'm an attractive guy, I'm intelligent, and can be damn funny. The problem is I wasn't showing women what I had to offer because my confidence was so stupidly low. I had sh1t in the past and my father was never real alpha. The women in my life (mom and grandma) conditioned me to be a polite sensitive boy as well. So, I realized fall semester that something was wrong. I'm this attractive, talented guy with a future, why is my confidence this shot. Well this site offered me advice my father was never capable of teaching me. I learned a whole new mentality when it came to women. I dealt with some of the demons in my past, and I hit the gym again. I also secured an internship with a top company and saw the fruits of my labor grow into fruition. I guess at the end of the day I realized I was the prize. I stopped psyching myself out when I approached women because of this, and the realization that hot women are by no means a scarce item.
So this site taught me the correct mentality. However, I have to say there was a lot of practice and nights spent on the phone with my friend talking about this stuff.
So when I walk through that door, I walk slowly, calm and composed, my posture is good, back straight and chest up, not many men dress as well as I do, and I possess an overall dominant presence that attracts eyes. I am in complete control of my life and I deeply understand this. I maintain this control when I interact with women too. I maintain the calm, aloof profile. But that said, I also use my energy with groups and entertain when I can. I make sure to smile and do not hesitate when cute girls give me a look. I make every effort to bring fun to other people's lives. And, when I can, I break the rules.
The worst thing that can happen is that the girl doesn't like you. If you hadn't approached her though, you would be in the same boat. So why not approach? Fail a few times and learn from your mistakes.
This is what happened, my thought process, and experience.
I'm grateful that the members of this site were able to teach me the alpha mentality that my father couldn't.
