Studentofthegame,
Bro, I just came out of high school so I feel I can provide you with some helpful advice. The thing with high school that I noticed was, the attraction girls had for me peaked early in grade 9 and every time I came back from summer holidays as well (albeit not as strong from the girls I met before since they already knew me from before), but new girls I never met were coming on to me. My point is, as Chase mentions, attraction is at it's peak early and dies down over time. I remember in grade 9 I felt like a rockstar getting all these cute girls chasing me, but as I progressed in high school, roles reversed as I was the one who was chasing the cute girls, which wasn't so cute to them

.
My advice is to talk to girls in high school and build relationships/friendships with the girls who actually offer value to your life.You need to gain some social experience in order to figure out who has the potential to be a valuable asset to your life, and who isn't going to provide you with what you need to keep improving yourself, if that's your desire (I know it's mine). With that being said, it's probably better to do pickup outside of school in general, but I know how tempting it is to talk to Sally who you've been eyeing for the entire year and who has the best breasts or ass in the whole grade. Don't worry, I get it

.
At my university, there are so many hot 8-10s, but I'm not approaching any of them this year. Why? Well the thing is, if you go to high school or a relatively small University, you tend to build a reputation, which may not be a great reflection of yourself. Therefore, I think the best thing to do in your case is to meet girls outside of school, and once your game gets tight and you've been closing girls/have abundance, then go for the girls at school. You'll get more attraction from them, and you'll be less likely known as the creepy guy and will build a reputation as a player, which girls find attractive believe it or not

Cheers,
Garrett
