I go to Starbucks a lot on my free time to relax since I like the environment there to code (I'm a software developer).

As you all know, a lot of hot girls come to starbucks and sometimes I see some really nice girls, which are just my type, sitting alone and I want to approach. I reach the point where I really want to talk to them but I just don't know what to say and I'm afraid of looking stupid.

I've noticed that when I talk to girls I meet through a common friend I get really good responses from them but i'm having some big problems with cold approach.

Maybe I just need some perspective only TRP can give. Any tips on cold approach?
