I’ve never done it. But I have been told that the instructor you jump with doesn’t stand at the door and wait. When you start walking, you are jumping.
Why?
Everyone has second thoughts about jumping out of an airplane.
The longer you stand on the edge, the more time for doubt to creep in. Decide before you board the plane if you are going to jump.
The same advice applies to every great adventure.
