michelangelo,
The "DJ way" that you talk about is pretty simple. It tells you that dating for men should NOT be pursuing, it should be ATTRACTING. You are the prize to be won. All through nature, males are the one made to attract the other gender. They will do their little courtship dance, twidde their little feathers, they will do things that will attract a woman.
People nowadays are a shame put to waste.
Some people will attract with thier skill, or their possessions, and that always works, but the way that people offer on this site, is to attract with confidence, boldness, challenge, and control. You shouldn't have to make an effort with a woman, she's the one making the effort to get to you.
The whole number thing is simple. It is JUST a number. If a woman will not hand it over after a few minutes of conversation so that she may have the chance to get to know you better later on, she is not relationship material. Even if she ends up being, you wouldn't have had as good as time pursuing someone that was truely interested in you from the getgo.
Here, a beautiful woman strikes up a conversation with you, you talk to her for a bit, she seems extremely nice, she has a lot of your interests, two minutes up, she asks for your number because she has to run.
What do you do?
You give it to her, you are simply attracted to her and you can't resist.
Another woman strikes up a conversation with you, not beautiful, but cute and sweet. She has some cute quirks, and you don't know much about her, but you're curious. She asks for your number, what do you do?
You give it to her. You are attracted to her and want to know more about her.
What is a situation you wouldn't give your number to a woman? If she was annoying and there was no attraction whatsoever.
You cannot create attraction. Some people are attracted to you and some people aren't. You should not change to attract them. But you should find out as soon as possible so you don't waste your time.
