why do you think some people learn a second language more easily than others

As we know, there are some characteristics that are important for our second language, such as intelligence, personality, and age. But, from my own opinion, I think the way of learning also plays very important role during the process of learning the second language. For example, some people who are the second language learning have a good ability to summarize and review what they learning, also good at how to get exactly information from the video and lecture. Second, the steps of learning should follow a normal way that the listening is first and speaking reading and writing after. As a result, those who have these two abilities learn a second language more easily than others.
