I think extroverted learner and introverted learner are an important role that influences the learning of second language. For example, students who are easy-going and self-confident are fearless when they communicate with foreign teacher and including other foreigners. They will not worry about the mistake when they speak wrong and at the same time, they always ready to learn and solve that they wrong. We can see that extroverted person will make faster progress in learning of second language. Every day they try to improve self and their English language skill are constantly improving. It makes them feel enthusiastic all the time.
