Abcone,
I'm going to suggest that the very fact that you're really striving for results is sabotaging your degree of success with intelligent woman who can intuitively sense an air of neediness or affectation in your approach and demeanor. Also its important to realize that no matter how good you are, you're always going to have off days. Don't worry about it!
1. Try going in with the Mindset of: "Im here, Im well dressed, Im smiling, Im down to make a couple new friends but I don't NEED her phone number". The "I want you, but I don't need you" or the "You're cute but I can get 10 of you" mentality really helped me improve my overall presence. The moment you fully internalize the "I dont give a sh1t" mentality is the moment woman start asking YOU for your number and closing themselves. No joke.
2. Try dropping the situational Opener and conversation stacks. Simple is Sexy. A confident "Hi" and a smile is all you really need to initiate the chat and generate interest. Once she responds, treat your situational opener as Plan B: a bridge to begin asking her 'what' and 'why' questions about herself. Conversational routines come in next - if needed - to fuel the otherwise organic, fun conversation.
3. At the Mall:[/b] warm up by chatting with retail clerks. Both men and woman. Kiosk employees are great because they often approach you with their sales pitches. Begin bantering with them and when a cute girl walks passed pull her into the mix...BOOM. Ask for her opinion on whatever product the salesperson is selling... insert humor. Banter banter banter! Sunglasses, Hats, and Cellphone accessory kiosks make for great fun. Ya digg? I guarantee that if you're a fun guy, with this technique alone, your success will double.
How exactly do you go about asking woman for their phone number? Maybe a simple change in wording is all that's needed for better consistency.
