Thx, New Voice!
This Mao's teaching may stress overmuch the importance of practice. Based on my experiences, it is convincing. I have no advanced degree in Chinese Language or English, many of the complete,systematic and academic knowledge I am required to learn as one faces job concern, but in a particular area, what I have mastered is a dream for those authorities.
But again without proper study my writing would be weak, to share with someone is a choice, maybe.
