And if they actually get a shot, to get in and to STAY 1A kids (shoot, all kids for that matter) need to remember these more than anything else that has been mentioned.
1) Better have your grades right and be prepared for college academically.
2) Be ready to work hard, swallow your pride, change positions, play defense, do what your coaches ask.
3) Get used to the fact that you ain't the big man on campus anymore.
4) Don't run home to mama / girlfriend.
5) Survive the culture shock. You are gonna be around people that think, talk, act, and view the world differently than you do. Learn to deal. Grow from it.
