Always be able to kill your students
You must throw away your bad habits to get good.
Nature is your friend; it helps you to win. Your enemy will have unnatural movement, therefore you will be able to know what he is going to do before he does it.
Any place we can breathe, we can do Ninjutsu.
You must be on your toes constantly, yet be relaxed.
No more talk. I'm sick of people talking. Train.
