This document discusses factors that affect language learning strategies, including motivation, age, learner beliefs, intelligence, and aptitude. Motivated students tend to use more strategies, and career motivation impacts strategy choice. Younger learners may develop fluency faster informally, while older learners progress more rapidly in formal environments. Learner beliefs based on past experiences influence strategy selection. While intelligence plays a role, it does not guarantee language learning success. Aptitude predicts potential but successful learners are not always strong in all aptitude components.
