You need confidence in YOURSELF so that you can be who you really are and trust that it will work etc. This is the confidence women want. They want you out on the line otherwise there is nothing for them to be attracted to. If you don't have confidence in yourself it doesn't matter if even they approach, you will push them away.

Confidence in yourself means that if your perfect match girl did come up and she was going for you you'd make it work. That is the check you should be thinking about and then just searching for that girl.
