Well, we all feel this way sometime in our lives, so don't feel so bad about yourself.
I haven't had much success with women in past, but now
It's started to get a lot better and it surely does feel great.
Maybe your not finding that spark, because your probably looking in the wrong places.
Try different environments that you normally wouldn't go to, and you'll
find various personalities that you normally wouldn't come across.
Pick your opportunities carefully and don't limit yourself to just one location.
