However, ( 7 ) Mozart produced in his early years is not considered to be particularly outstanding. He didn't produce his first true masterpiece* until he was 21; pretty s young to be sure, but Mozart ( 1 ) already been composing for years by this time. 10 The figure of 10,000 hours has been suggested as the amount (1 of serious practice or study needed to truly master a skill. That is nearly two hours a day, every day, for 14 years. Natural ability is, of course, an important factor in success, but even someone as talented as Mozart couldn't become a "great" composer until he had put in* 10,000 hours of hard work. The same can be said of golfer Tiger Woods and computer genius Bill Gates. Most people in developed countries can expect to have a healthy life of at least 70 years, or 613,608 hours. Although that seems like a ot of hours, most people spend about a third of them asleep. Take way all the hours we "lose" moving from place to place, eating, etc., well as the time spent at work or school, and the amount of free me we have starts to look quite limited.

Communication English II Lesson 7 Encouraging Song Section 1&2 Reading Passage Section 1 There are many songs that help people overcome sadness or troubles. Makenaide may be one of them. This song has been encouraging many people for a long time. The lyrics of Makenaide were written by Sakai Izumi, the vocalist of ZARD. It became a hit in 1993. The following year, it was adopted as the theme song for the National High School Baseball Invitational Tournament. Some schools have also been using this song for graduation ceremonies. When the Great Hanshin-Awaji Earthquake occurred in 1995, this song was often aired. Many people were able to recover their spirits by listening to it. The song also cheered people up after the Great East Japan Earthquake in 2011. Unfortunately, Sakai passed away in 2007. However, this song is still popular today. Section 2 What makes this song so attractive? The answer may be in its lyrics. The song has a message of hope for everyone. Let's take a look at the first refrain. Sakai left a piece of paper on which she wrote the lyrics. It shows that she changed a part of them. She replaced the words "Don't stop until the end" with "Keep on running until the end". She may have thought that this sounded more positive. Handout Reading No.15 Text p.94-97 She changed this part while she was actually recording the song. "Which words communicate better?" was the question she always had in her mind. She always searched for words that would encourage people. Don't give up! Just a little farther 負けないで もうすこし Keep on running until the end 最後まで走りぬけて Even though we may be apart どんなに離れてても I'll stand by you with all my heart 心はそばにいるわ Follow the dream you'll catch in the end 追いかけてはるかな夢を 1.
