So once you break your childish anxiety to talk to girls you will understand that getting a number is the easy part, maintaing a conversation on the other hand is pretty difficult. Here are some tips that i learned that helped me, post your comments or opinions!!

Frist understand what you hate/love in a texting convo then apply that to your game. Understanding this will help you maintain your cool and not send stupid texts runing your chances, For instance;
Personally i hate;
Girls that don't respond quickly to a text
girls that just answer my question and don't ask me a question back
girls that ignore me
girls that play stupid

Things i love ;
when a girl intiaties a convo
asks me lots of questions
says i am sweet

Here's how to apply, its pretty simple the more i do the things i don't like to her means she will appreciate the things i like that i can do to her. hopefully not to confusing but its pretty simple its like a dog if were are to sweet or give to many treats then the dog isnt going to want the treat as much because he knows he has it whenever. Same goes for texting here are my rules:

Never ask questions (once in awaile is ok, but your not her parents)
Never respond so quickly
never use to many smiley faces
never use alot of negs
try to maintain a conversation where she is wanting to talk to you!
be the frist to end it so when she texts you back the ball is in your court
try to be "fake" boost yourself in the conversation so she can be excited to tell her friends what you do and how great you are

Of course once you have been talking for a long time the game changes, but let me know what you think!
