I'm going to state the obvious first, this isn't part of the Four. Find a Hypnotist who is skilled in NLP, destroying anxiety and never thought patterns are the first and last things you learn in becoming a practitioner in one session in one hour, they should be able to turn a lifetime of anxiet into a future of prosperity.

Now with the methods.
If your approach anxiety comes from a fear of rejection, I am going to do a little promoting here.

1. Effortless Seduction With Little To No Rejection: effortless-seduction-techniques-with-li ... 23206.html
Imagine being able to recognize signs that tell you she wants you to talk to her, to say something, and you know for a fact that you will not get a negative response from her before you ever approach her. This post that I wrote here, explains the body language to look for from the woman to tell you she is ready to approach.

2. Akido: A martial arts technique that is meant to take your thinking from you heard to your body. It will quickly and easily relieve stress, anxiety, and nervousness. And it's something you'll be able to do without ever having to look weird, and you'll be able to do it on the spot. The technique is simple, you take a deep breath, rate your anxiety, and then shift your focus to your shoulders, your chest, your stomach, your hips, your legs, your calfs, right to your feet, until you can feel grounded. Then rate your feeling of anxiety. Now, a simple way to anchor this, is to press your index and thumb together. So, imagine a time when you were really anxious, really nervous, your entire body couldn't move, even though you wanted it to, rate that feeling 1 to 10, and let your focus slide down, and keep doing it until that feeling is down.

3. Are there any environments where your really confident at. Are you in the know it all in a classroom, are you a sci-fi nerd who shows up everyone with your knowledge of Star Trek, are you a reader who can talk to people about interesting books that they're reading. Is there any time in your life where you are able to talk to anyone, because you're not concerned of what they think. Find that place and close your eyes, and see where you see that in your vision. Now then, take the times in your life where you were stricken with anxiety, close your eyes get a vision of them, now consider where they are in relation to the positive one. Put your hands out in front of you, and look at both of them, with your eyes shut, and imagine one in one hand and one in another, because your anxiety is a natural part of who you are, it's meant to protect you, keep you safe, but it's just overdoing its job, and you know this. Tell your anxiety that, that you know it's just there to protect you, but it's over doing it's job. And slowly, take both images and push them together.

4. Okay, think of a list of thoughts that go through your mind when your becoming anxious. Write them all down. Loser, Ugly, Fat, Not Good Enough, Freak... whatever they are, now, I want you to repeat those words in your mind, but do it with the daffy duck voic. Or porky pig, or some ridculous cartoon. And keep repeating them making the voice more and more obscure and ridiculous until you can't take them serious any more. Now, take those feelings you have, whats ever left, imagine your in a movie theater with a huge screen and you're sitting center row, now imagine your floating out of your body and into the projection booth, where you can watch everything safely. As your watching it play forward, those words echoing in your head, I want you to stop the projection when it comes to the end, and go back to your body, now run the projection backwards, faster and faster, through your head with the voices squeeker and more and more ridiculous, "I say, i say, I think you a losa," and keep running through the feeling until you feel great, do this 3 or four times. Open your eyes, and see how you feel.
