How to stop being afraid of speaking a new language

• Start in private. Say sentences out loud alone until your mouth knows them.
• Keep sentences short. A short sentence said smoothly sounds better than a long one said with doubt.
• Use a checker. Seeing that most of your words were right is evidence you can do it.
• Expect mistakes. They are how the language gets learned, and listeners care about being understood.
• Plan a small real conversation. Order a coffee, introduce yourself. Prepare the exact sentences.

Fear comes from being judged and from not knowing what to say. Practising privately removes both. By the time you speak to a person you have already said the sentence many times.
