Transition to Fish

I started surfing about 5 years ago and I'm 50 years old and in good physical shape. I started with a 9 foot long board and then transitioned to a 8 foot mid board then to a 7'-2" hybrid. I'm currently trying to ride a 5'-9" x 21 x 2.6 fish with a quad set up.
I knew this jump down to the fish wasn't going to be easy. My shaper told me that some of the challenges that I'll need to overcome was paddling endurance and getting into the wave. Well he was right on. Paddling the smaller board is really tough I'm getting better each time I go out. Also learning how to start paddling for a wave really early or waiting later hasn't been easy either and has been a eye opener compared to surfing a long board. I've been riding this board since Jan and most days I'm only catching a couple wave......on bad days I'm catching none.
One of my problems ever since I went down to the smaller board is worrying about the pop up. I'm so concerned about popping up and foot position that I now have a bad habit of looking down which as you know leads to falling off.
On slightly bigger waves (~5 feet) this issue isn't as bad since everything is moving so much faster I don't have time to look down and everything is fine and I catch the wave.
Do you guys have any tips to break this habit. I know you need to have chin up and look down the line. when do you guys start looking down the line? is it when your paddling for the wave? is it when you in the wave?
Seems very basic and no different when riding my longer boards but im kinda messed up right now.
Thanks in advance.
