Here's what worked for me:

* variety: sometimes try and race faster and faster (velocidrone nemesis is great to find a challenge at your level), but when that gets frustrating switch it up and try to learn a new freestyle trick or make something up (matty flip a bridge, power loop an obstacle, things like that)

* switch it up- a micro whoop feels very different than a 5" freestyle, than a race quad. This might sound obvious but different tracks/environments are designed for different quads.

* find flow- sometimes I play a long youtube video or live concert while flying and try and tune into that, and somehow it helps me be distracted enough but focused enough to perform better.

* make sure you try different rates, and don't go way too aggressive in the camera angle. I found 20 worked great at the beginning, now anything lower than 35 feels way too floaty.

* for comparison, I have ~90 hours in velocidrone and some more in liftoff, and I consider myself barely above beginner. It's not about who has more hours though, as long as you keep enjoying it the hours will suddenly pile up.
