The popular phrase "You can talk the talk but can you walk the walk?" applies perfectly to the way you approach a girl. As I stated earlier, what you say won't make a difference if your non-verbal indicators convey something different. Luckily, looking more confident just takes some work and practice until it becomes a real part of you.
Work on the following four goals and you'll notice a big influence on the responses you receive from girls.
Virtually nothing generates a more powerful first impression than a genuine smile. It exudes positive energy, is non-threatening, and shows you've got balls.
It frustrates me when I see a guy with a blank or stoic expression approach a woman. A lady wants to be with a man she can have fun with. She won't be able to unwind and enjoy herself if you seem anxious or tense. And if you don't smile, you can't expect her to reciprocate.
Use Strong Eye Contact
Confident guys hold good eye contact. When you constantly look down or dart your eyes anxiously, you're going to make her un-easy, too. Be boldly honest and communicate your interest through locking eyes with her. She'll find you more respectable and appealing.
Challenge yourself to make more routine eye contact with folks throughout the day. Soon you'll have no problem employing this to situations with ladies.
Establish a Clear and Strong Voice
Slow down and speak clearly. Almost everyone talks too quick and thinks that if they aren't rushing, the girl will get lose interest. It's actually the contrary. A woman can't create a connection with you if she's struggling to comprehend what you're talking about. Talk with purpose-- it draws her in and hides any nervousness you're experiencing.
Learn to project from your diaphragm and not from your throat. You will have a more powerful, resonant, and attractive voice. Start by practicing diaphragmatic breathing, it takes a few days to get familiar with it. When you are using the right muscles, your real voice will begin to come out. I listened to Roger Love's Vocal CDs in the car during my commute and they transformed my voice.
Display Self-Confident Body Language
Stand up straight, shoulders back, and head up. Move smoothly and deliberately. This means no fidgeting, no abrupt movements, and no awkward shuffling to and fro.
Open body language is friendly, so don't be scared to talk with your hands. Using gestures in a conversation keeps things exciting and shows that you're passionate and personable. It'll only be normal for you to improve and extend those gestures into touching her (such as on the shoulder or back.) Just be sure to keep your hands only in appropriate spots.
Remember, you don't need to get overwhelmed and try to work on this all at once. What worked for me was to initially focus on one or two points that I needed improvement on. I saw a difference right away and it became easier to include the rest later.
The only way to improve is to start.
