I don't care who you are, everyone needs improving. Its like telling a doctor they're fake smart because they had to learn first in school instead of being born a doctor. Learning how to deal with woman, yourself, and life are no different. 
lol times 2......even texting game takes practice.
....rule of thumb- 
-how ever long it takes for her to respond to me, I wait double. 
- always have the last text
- keep it brief but when you can try and be a bit sexual
girl hasn't texted you in a while, and you know she's probably not going to respond to a casual "hey,whatsup" you need to  reverse it. 
", Im sorry i havent texted you in a few days .."
it pisses them off to end, ..cause you know their thinking "this  jackass really thinks i was sitting around all week for him to text me?? i wasnt even gonna talk to him"
its all about manipulating the girl and  forcing  her to give you the  response you want.
