Listen man, you're gonna be nervous, especially during AFF. Even if you weren't nervous or scared about the jump, chances are you'll suffer from performance anxiety... worrying about how you perform what your instructor told you to do. (nothing sexual, that could become a lawsuit) The only way you'll shake the pre jump jitters on every jump is if your jumping a lot everyday... then you may become complacent like me. Hell, what's the worst thing that can happen?
