假如你是张伟，你的好友王楠因不擅长与他人交流，感到非常苦恼。最近，他来信向你求助。请你用英语给他写一封100词左右的回信。 主要内容包括：
1．劝他不必为此事感到苦恼；
2．告诉他与别人有效地交流是很重要的；
3．就如何改变目前的状况给他提出几点建议。
注意：信的开头和结束语已为你写好， 但不计入总词数。
Dear Wang Nan,
I know you are feeling annoyed these days because you are not able to communicate with others effectively.
                                                                                          
                                                                                          
                                                                                          
                                                                                          
I hope my advice will be of help to you.
All the best.
Yours sincerely,
Zhang Wei
