From A Weak to Confident Communicator - 30 Day Challenge
Many people worry about talking to someone who has superior vocabulary and communication skills. If you have the same fear, the anxiety stems from being judged and compared.
But people do not judge your words and sentences at every possible occasion. At least most good communicators don't. By overcoming this fear, you can take a cue or two from a better communicator and learn yourself.
Today, you must start a conversation with someone who speaks the language better than you do. As you speak, pick one attribute from the other person and try to apply it yourself.
