Just to prove there ain't nothing new under the sun, I recently found a book on improving your judo through hypnosis - published 1925.

Sashinjutsu Ōyō Sokusei Jōtatsuhou Jūdō Hōten
円尾, 帰心
Maruo Kishin

Nothing much else has worked for me.... maybe this will do the trick, if I can stay awake long enough to read it.

Perhaps folks can post other books on MA hypnosis; I know there are tons on sports in general but don't know about martial arts.
