As Wendy stated this is an expensive way to freak your self out.
Question for you
Why do you want to be brave enough?
You are literally risking your life for fun. Skydiving is not for everyone, no life threatening sport is. I have 20 years jumping and that;'s not where my fear lies. There are many sports out there that scare me too much to undertake.
I'm brave enough to skydive by not near brave enough to do other things.
Brave enough is not the way I would gauge what I risk my life on..
If skydiving is that scary to you, you don't have to do it. You certainly dont have anything to prove to anyone.
You jumped already that's more than most people on the planet will ever do.
