I thought I was crazy, at the last second my body would flinch right before I threw the ball and I thought about it constantly.
I don't know why the wires got crossed in my brain but the research I did made me believe my body was trying to keep me safe. I know sounds crazy.
Once you realize your ego is threatened by something so trivial you can hopefully laugh about it, and slowly allow yourself to just throw. If you launch one, it won't kill you. Even if it feels like it in your head. Give it some time.
This video was spur of the moment and gets cut off at the end but hopefully it at least helps you see that a perspective change makes all the difference!
