When I was learning cartwheels on high beam, I just pretended I was Nastia Liukin and that I could do everything perfectly.
Kinda silly,I know,but it worked! :)
I started when I was 11 at a bad,bad gym.
They taught me absolutely nothing,but I stayed there 3 years.
Now I'm in another gym,wich is excellent,I improved so much.
But I'm 15 and still a level 6.
