So when I call or text a girl and a date isn't set up... I've decided I have to go get 2-3 more phone numbers before I contact them again.

I literally create more abundance of women in my life. When you continue to contact a girl, you cause yourself to care too much.

Get to a place where you have to write down on paper all the girls you are talking to. A place where you have trouble keeping track of them all. They'll notice. Some of them will probably even contact you first.
