I also at some point started to never think about a girl too much until I've slept with her. Guys will fall in love with photos and a few messages of a girl on a dating website without even meeting them. It's natural but pointless. I can't be bothered with waiting around so I always have a few backup girls as a plan B and just get on with my life. Sometimes you get a nice text from a girl and you want to respond instantly - you just have to get in the habit or ignoring it completely sometimes. Its not life and death, there are other girls out there. Im not afraid to experiment on one girl to see if something works or doesn't because the results I can use further down the track. Its hard not to be a nice guy sometimes but ultimately its better to be a smart creative guy. A lot of guys fear asking a girl out too soon but I relish directly approaching girls and putting them on the spot. They have to say yes or no straight away - I know the odds are going to be yes more than no and you are sweeping them off their feet if you do it right. Less is more.
