OP:
As has been said before herein, anxiety (it can be positive or negative) is the product of potentially fulfilled or unfulfilled need and expectation.
Common needs include, but are not limited to: companionship, sex, friendship, fellow-feeling, mental stimulation, social validation, entertainment, amusement.
Common expectations include, but are not limited to: this person will like me, this person will not like me, this person will accept me, this person will reject me, this person will fulfil my needs, this person will not fulfil my needs, I will/will not fulfil this person's needs and expectations.
Negative anxiety accumulates in to desperation as results of unfulfilled need and expectation. As Pook says, 'Kill the desperation':
"Being a Don Juan is not a net sum of smooth manuevers and methods but of your own outlook on the world and on women. ANYONE can memorize 'techniques', but FEW can change the way HOW they think. Women will be able to sniff out the former. But with the latter, women will be clawing each other for you. A Don Juan is a state of mind, not a list of methods and tricks."
In short, approach for the sake of approaching, because it's fun, because you want to. Yes, your needs and expectations are driving you, but they need to be latent manifestations, rather than overtly conscious motivations. It is difficult to explain, but the message always pedalled, which I agree with it outcome independence. Getting a number, a kiss or a even a lay should be inconsequential to the act of talking to a woman. It may be a consequence of talking to a woman, but one needs to forget that at least consciously, in order to realise the consequence.
Your anxiety is
solely born from your consciousness of potential consequences of your actions and the impact of those consequences uopon your needs and expectations. If you haven't try The Book of Pook. For me it is as good, if not better than the DJB.
