In my experience the key is to figure out what they are looking for. Some just want to hook up, others just want some attention, and others are actually looking for a relationship. In my opinion if you click, have chemistry, the feelings are mutual, and your both on the same time table/looking for the same things it is pretty hard to mess those situations up.
I had a really good couple of dates about 1.5 months ago with the same girl and we felt and clicked instantly. It didn't work out which is cool but at minimum it helped me believe that finding someone is definitely possible.
