    I have been feeling tired these days and often find hard to concentrate on my study. My teacher told me that it was the sign of anxiety. She advised me to read an article about reducing tension and improving brain efficient. I listened to her and found some useful ways in it. I began to form a habit of taking a nap for 15minutes at noon and try to spare 30 minutes a day to get move. A walk on the playground was beneficial. Besides, following the author's advices, I would play words with friends during class break, which made the brain refreshed and worked better. Having fun with friends is really a good way of becoming relaxed.

    Being tired may influence our mood though it has positive side. The brain can be the more creative. The author reminds what we should not fall asleep with brush in hand and we had better do something creative.
