It is said that one should not hesitate to correct himself when he has made a mistake. If he corrects himself without the least bit of delay, his mistakes will disappear.
Yamamoto TsunetomoSincerity does not only complete the self; it is the means by which all things are completed. As the self is completed, there is human-heartedness; as things are completed, there is wisdom. This is the virtue of oneโs character, and the Way of joining the internal and external. Thus, when we use this, everything is correct.
Yamamoto TsunetomoThere is not a man who does not get senile by the time he reaches sixty. And when one thinks that he will not be senile, he is already so.
