Wen Zhiming came to the Thousand-Character Works, with ten copies a day as the rate, and the books made great progress. I have lived in a book all my life, and I have never hesitated, or answered people simply, and I will never tire of it again and again, so the older I get, the more subtle I become.
(from the Chronicle of the Book Forest)
Translation
Wen Zhiming, a calligrapher of the Ming Dynasty, copied the Thousand-Character Text and practiced it according to the standard of writing ten books every day, and calligraphy improved rapidly. He has never been careless in writing all his life, and sometimes he is a little dissatisfied with answering other people's letters. He must change it again and is not afraid of trouble. Therefore, the older he is, the more exquisite and ingenious his calligraphy becomes.
