Listening is the first step towards learning any language. That is how babies learn their mother tongue. The next step would be trying to replicate what you hear. Looking for the meanings of the words and then reading. Practice makes a man perfect. Without feeling intimated by being judged by others, freely practice and speak, even if you know you probably may be making mistakes. It's fine as long as you wish to correct yourself and learn.

Communication is all about confidence and clarity of thought. In contrast, we must have a good command over the language; it is also crucial that there should be a willingness to maintain a continuous learning process. You can be an effective communicator if you can express and engage in your communications, be it, verbal or written.
