It's all about status and popularity at that age. (Actually at my age, it's still about status and popularity in the working world lol. People never leave high school LOL. But that's another thread.)
Thinking WAY back, four types of guys did very well with the girls:
1. The athlete whether it's football, basketball, baseball or any major sport at your school. Bowling doesn't count lol.
2. The good looking guy. He might be tall or built or just have pretty boy looks.
3. The life of the party guy. This guy is the best talker. He ALWAYS has an audience hanging on his every word.
4. The rich kid. He drives the most expensive car in high school.
While you can't control #4, getting involved in a sport will give you #1, get you in shape like #2, and give you a social circle sort of like #3.
What do we preach here to more mature guys? Work out which is related to #1 and #2. Work on your game and/or speaking skills like #3. Work on your career or business, sort of like #4.
So the principles don't really change much.
