Don’t worry about tomorrow. If I completed what I should do today, tomorrow would be fine.
   We always spend time on complaining or worrying. We can use this time to do something useful. Only if we try our best today can we achieve our goals.
   Our school holds the competition of singing every 2 years. I join it because I love singing. But I saw someone who was very professional at singing join it too. I was nervous and worried about my ability. I had no confidence. My mom noticed that, saying,‘Where there is precaution, there is no danger. Just take it easy. It takes many days for water to freeze three inches deep. No one may succeed without long time preparation.’
   I realized that I should try my best to practice my songs and concentrate on my task. So I sang my songs everyday and kept my mind peaceful. When it was time for the competition, I did well in it without disturbance. In the end, I won my prize and was filled with happiness.
   It’s obvious that one who always gets ready can overcome all kinds of difficulties and take hold of chances to become successful. Therefore, we needn’t be worried about the future because we have made our greatest efforts.
