I felt a bit tired yesterday. I was reading an English-Japanese dictionary and trying to remember words, the number of which is over 13000, and then I felt bored to do. I am apt to throw away to study when I feel it goes too long for me. The speed of reading is very important for me to keep my motivation. This time the dictionary is over 500 pages and I couldn't pass through it easily. That's why I was tired. Though I wanted to do other things to my heart's content, I am going to take TOEIC test next weekend. So I will continue it for one more week and then I will do something I want to do.
