When you are learning a new technique, practice it wholeheartedly until you truly understand it.

Don't pretend to be a great master and don't try to show off your strength.

When you leave your home, think that you have numerous opponents waiting for you (it is your behavior that invites trouble from them).

Any man will be able, after sufficient practice, to accomplish remarkable feats of strength, but he may go only so far and no farther. There is a limit to human physical strength that no one can exceed.

There is no first strike in Karate.

You must be deadly serious in training. When I say that, I do not mean that you should be reasonably diligent or moderately in earnest. I mean that your opponent must always be present in your mind, whether you sit or stand or walk or raise your arms.

In the past, it was expected that about three years were required to learn a single kata, and usually even an expert of considerable skill would only know three, or at most five, kata.
