Talking to girls can be an exercise in anxiety, panic and fear for some guys because of the imagined consequences of failure including rejection, ridicule and a lowering of further lowering of self esteem that can ingrain a self defeating attitude.
How to talk to a girl is not that hard though if you know what women respect and want and how to produce that in yourself.
Many guys have turned to internet dating and single chat lines to improve their skills at talking to women but this is like riding with training wheels because the anonymity of the internet gives you a false sense of security and confidence that real life strips bare so i do not recommend this as it makes bad habits if you want to do this in the real world.
The trick is that girls are attracted to guys who are fun, mature and confident and many men who think they know this do the one thing that ruins their chances and put on a false confidence that comes off as arrogant bravado which to a women who is any judge of character realizes is a way to cover up insecurities they do not wish to show.
So what is the solution? How do you talk to a girl and come out of it being an object of desire and not a loser or what can be even worse a "friend"? The first thing you must do it to realize that the confidence that women look for comes from your entire attitude which means that you must be comfortable with who and what you are and not worry what others think of you because only then are you free to be yourself and not try to be someone else and it shows in everything you do and every word you say.
