It is often difficult for naturally introverted people to develop their oral skills. They are often good at reading and writing, but lack of practice in speaking completes the cycle and makes them even more shy and anxious. Try to develop your oral skills indirectly, for example, with the help of the social media. Writing emails, texts, blogs and joining chat groups could increase your confidence. Look out for small, safe groups in encouraging contexts where you will feel more comfortable practicing your oral skills.
