I dont tell myself anything anymore, I see a girl I want to talk to and I walk over and blurt out Hi, Hey, Whats up, or hey whats up, With a sly smile that screams I think your f.cking hot and I would like to hit that.
Stop thinking, my best moments have happened within the last few weeks for me, every girl I meet is smiling at me and trying to keep me talking to them. Just turn your F.cking brain off, you dont need it analysing every thought. Do what feels natural. Girls dont think, when they talk to you, they just react and blurt out things, ever heard a girl say something stupid?
I see a girl I like I walk up with a smile say hey, hold out my hand and use something situational to start a convo. Then just carry on from the last line they gave you. Its easier then you all think. Girls will talk and talk and talk, and all you have to do is interject once in while to agree or disagree with them.
Keep the topic light, if they start to get serious about something, say there career and what they want from it, you say "Ok enough career planning, lets talk about something more fun, whats your favorite color?" everytime I use this the girl enthusiasticly replies with her favorite color and it brings the conversation back down to a lighter more fun topic.
Just talk, about anything, but keep it light and smile.
Also you need to stop giving a f.ck what some girl thinks of you, shes just a girl, a giggling, smiling flirting girl that wants to be a part of someone elses world(yours). Who cares what she thinks of you, you have your life, which is complete and makes you happy with or without her(it does right?).
Get the right attitude and then the girl doesnt matter, shes an object now and objects dont have opinions. If she fits you good if she blows you off good, she doesnt even give herself a chance to f.ck with you.
