You need to write a book, what's going on with my serve. It's disaster. I don't bend my legs. Instead of jumping forward, I'm kicking it too much instead of hitting it. ... I drop my head, I don't hold the left arm. It's so much, that you just - I don't know. I know this, and I'm still so stupid that I continue doing it.
