I think the going rate is about 10%, so I read. Just remember that most of the no responses have nothing to do with you. Some women are looking for some specific attribute e.g. a guy who plays tennis, are ambivalent, are looking for validation...there are a ton of reasons women don't respond that don't necessarily have anything to do with you. Now, I would suggest you try different approaches and see what happens. A book I like is "I Can't Believe I'm Buying This Book" by Evan Marc Katz which helped confirm for me that I was doing something right lol. I'm not crazy about some of his examples of witty things to say to women but that's him not me. I also find that through messaging for a few days or a week you get a feel for the person. When I get "have a nice day" a few times and not much else in response to my chatty message then it's time to move on. Again, I find the crazy comes out real fast and I'm glad I didn't go for the coffee meet too soon. Anyway, hang in there!
