Recently, I decided to challenge myself by memorizing 100 English words every day, and I am proud that I have successfully maintained this habit for 30 days. In my opinion, building a strong vocabulary is the cornerstone of mastering a language, because words are the basic materials for constructing sentences. Moreover, a wide vocabulary allows me to read magazines and books with greater fluency, which makes the reading experience more enjoyable. Finally, knowing more words increases my confidence when I communicate with foreigners in English. To sum up, this habit not only strengthens my language foundation but also motivates me to keep improving.
