"Do not make mistakes" advice.

Antimoon is a website that sheds light on how Tomasz P. Szynalski and Michal Ryszard Wojcik, both polish engineering students, learned to speak English as well as native speakers. It provides advice to learners of English as a foreign language, one peice of advice, the most controversial, of which is “Do not make mistakes”, the most controversial advice. Their assumption is that every time we write or speak with mistakes, we reinforce those mistakes and we develop bad habits according "You can damage your English by writing and speaking" article. And the website Antimoon advocates massive listening and reading in order to feel sentences which sound natural or weird to us.

However, to be constantly afraid to communicate could lead to bad habits such as the over correction. As a result, such learners may speak hesitantly often self-correcting in the middle of utterances, and are so concerned with correctness that they cannot speak with any real fluency.

Could shadowing and copycat techniques lead for to better more correct and natural phrases?
