I was recently at Catalina Island trying out this Fly boarding thing. It was a challenge for me to learn how to use this at first. I kept falling and have several bruises to prove it. The one thing that I kept doing, was that I kept getting back up to try again.
The thing that helped me out the most to learn this new skill quickly and at an accelerated pace was to close my eyes and visualize myself on the board doing all of the movements perfectly. I also referred back to when I was learning how to snowboard and surf and those references helped me to tap into my muscle memory in order to learn how to do this jet fly board without falling so much.
That’s what I would recommend for you to do. Try something new, close your eyes and visualize yourself doing it perfectly, then try it again. Repeat this process until you’re doing the activity at a subconscious level.
