I have lack of material for young PUA's i hear you cry lol Im a young Pua and often find stuff that i read or watch doesn’t work. BTW peackocking at any age works it just makes you stand out. Really man do it! (just not with a big mystery hat lol)
The best info you can get for the younger stuff, is collage game. Heartwork, Ratisse, and Hshudo are good ones to look out for.
Im young and quite developed at PUA

so if you do have any questions, feel free to E-Mail me.
For immediate help do you can......
1.Peackock but you will only pull it off if you are completely ok with it. Its the easiest way to get noticed, and get girls come up to asking about your stuff, therefore you dont need to approach them.
2.Dont go for the hot ones yet! climb up the social ladder but befriending the less attractive girls. Hang out with them. If you show your a cool guy in a school lacking in boy the hot girls will be easy to open.
3. Get on the Scene. That means parties, football matches, debate clubs, get your name round the school as this cool guy
Hope this helped and if you need any more help just ask
