I think I've been through the same trepidation as yourself, in fact with about every jump on my AFF there was always something new to learn, something to worry about, from going out not being strapped to someone, to going out and doing different exercises to first solo jump.I can tell you with my vast number of jumps,19 now, that it just gets better and better. At various stages I would be thinking, I'll just finish the course then I won't do any more, then I'm thinking I'll only do the 1 or 2 to keep in date, then I'm thinking I'll only do the 2or 3 today and now I absolutely cannot wait for my next one.
