Second Language Acquisition (SLA) is a multi-dimensional and dynamic process that is influenced by numerous factors. Individual differences are undoubtedly the most significant factor. Individual differences refer to the differences in cognitive levels, learning styles, motivation, and emotional attitudes among learners during the process of acquiring a second language. These differences have a significant impact on various aspects of language learning, and this is especially true in English writing teaching. English writing is a very complex language skill that involves students’ language knowledge, as well as their certain thinking abilities, creativity, and expression levels.
