Lacking attraction in conversation

During my experiences approaching women and attempting to even have a decent conversation I seem to be encountering the same problem over and over. They don’t seem very interested in what I have to say, they always seem to show negative body language and obviously the conversations don’t last very long.

I think I need to try out a more direct approach. Something along the lines of “Hey, I saw you from over there [point], saw you and thought you were cute, wanted to say hi so… Hi”

As soon as get the balls to do it I’ll let you know how it goes.
