Wakeboarding

It's almost the 20th ride for my Wakeboard sessions. I've been going for Wakeboarding almost every week, and sad to announce that I've not been progressing much. My Wakeboard seniors told me not to look at the water when I am on the air and during the landing. I've tried not to look at the water during landing, and I still failed in my landing. I'm still trying to improve on my wakeboard. I know where's the POP of the wake and I managed to get a lot of hang time at times, but it's inconsistent as I'm not experience on where to execute the POP.
