Use every learning opportunity
There will be times when you know your English isn’t quite right. Perhaps someone can’t understand you, or they ask more than once for you to repeat what you have said. This can knock your confidence. Don’t let it. Use it as a learning opportunity. Take your time, and see if you can make yourself understood. Point, draw, act out the meaning, and see if the person you’re talking to can help you out with the words you are missing.
