I am coming to the end of month 10 since I started,
and I "hit the wall" a few months back as I tried my first flying gybes,
they seemed quite impossible, and I ended many days thinking I may never progress,
then it clicked, however, toeside runs became scary fast rides to doom,
then when I tried smaller kites but more speed at the turn point,( not easy and requires a leap of faith) and a go for it resolve, suddenly with a smaller kite I was able to hold my line upwind and even tighten my angle on each days practice, and within a week or two of hard practice, able to water start on toeside, carve around sizable waves and even sail straight over high pointed waves and drop down the steep back side with a big smile and then use the next big wave as a ramp to switch back to heelside with speed and confidence then switch back and repeat over and over,
I was in heaven yesterday on my 6mtr yet again, sailing in conditions and with so much confidence that seemed impossible only weeks back.
my aim now is to learn the foiling 360, and my target is this year sometime.
Age is not a barrier, I am 64 this year, but 4 days in the gym each week and now more flexible than I have been for years I can't see any foiling moves that I won't master in time with lots of practice.
I do believe the biggest barrier to progress is fear, especially after bad crashes with speed, the most off putting experience for me was the toeside death run on a tall mast with not enough skill or nerve to be able to carve around or enough nerve to just press down and point further downwind to outrun a pushing wave, that just seemed to scary hard to even think about.
Time on the water and in challenging conditions.
If it does not challenge you, It will not change you.
