You really think 3 months of training can get you good enough to be the best of the best on your team? Idk what shitty ass high school you go to but that's not the case. Football, basketball, baseball, any of those sports take years of experience to develop the necessary attributes and sport IQ. Sports like track, cross country, swimming? I'd like to see you try and bring your 5K from 18 minutes (fairly competitive) to 15-16s (States-bound) in 3 months. It's impossible. Same with your mile time, 400m sprint, 500 yd freestyle, whatever.

I will say that it's good to study good social interactions, but scripted movies are not a good source. Don't you hear people saying how Hollywood is not like real life? Those millions of dollars go towards writing what's entertaining, not what's reality. If you wanna learn how to socialize, then make friends and socialize with them.

One last thing, it sounds to me like you're dickriding these stereotypical high school jocks pretty hard. They're not out fucking, partying, having a good time 24/7. I'd believe that about actors and musicians, not high schoolers.
