This morning I recommended a book on earth science, which I read on my way to and from work. Earth science is a topic that appears most frequently on the actual TOEFL test. If you are not good at listening comprehension, a little acquisition of this type of knowledge will be a big plus. Well, what I wanted to say is something different. One of my friends and co-workers (teachers), who is also the coauthor of our previous book, has already ordered the book from amazon.com. It was just a matter of 30 minutes or so after I posted the recommendation. See? This is what distinguishes successful learners from unsuccessful learners. Successful learners always do. They are doers. Unsuccessful learners always think. They are thinkers. However, when you think about the book and decide not to read the book, isn’t it just like you didn’t think about the book at all in the first place? You will learn nothing from this act. On the other hand, successful learners can always learn from their deeds. That is partly why the above coworker is also a respectable translator.
