One of the most important characteristics of successful language learners is their willingness to make mistakes. Young children learn their first language by trying to communicate a message rather than by trying to learn grammar rules. Children are not worried about correctness, they are concerned with the message. The message is more important than the grammar. In the same way, second language learners must try to communicate even when they are not certain of the correct forms or words. By using the language to communicate, their language skills will improve. For example, if someone else cannot understand what the learner is trying to say, then the learner must change the way he or she is using the language. In this way, the learner quickly learns what is correct and what is incorrect. Mistakes become learning opportunities. Therefore, the more learners use the language, the more skilled they become in the language. Successful language learners do not wait until they can speak or write perfectly before they use the language; they use the language in order to improve their speaking and writing.
