[EX Q]: Article: On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man. The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever. Soon he was surrounded with people who were attracted by the words on that paper. It said, "Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim it soon." After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, "Yes, it's you. I knew that you were an honest man and would certainly come here." The young violinist asked calmly, "Are you Mr. George Sang?" The man nodded. The violinist asked, "Did you lose something?" "It's a lottery ticket," said the man. The violinist took out a lottery ticket on which George Sang's name was seen. "Is it?" he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist. The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, "At that time you needed money to pay the tuition and you had to play the violin in the railway station every day to make money. Why didn't you keep the lottery ticket for yourself?" The violinist said, "Although I don't have much money, I live happily. But if I lose honesty I won't be happy forever." Through our lives, we can gain a lot and lose so much. But being honest should always be with us.

[EX Q]: Article: Characters in novels don't always do what the writer wants them to do. Sometimes they cause trouble, take on lives of their own, or even work against the writer. It's not just a problem for inexperienced authors: famed children's novelist Roald Dahl said he got the main character in his bookMatildaso "wrong"that when he'd finished his first version, he threw it away and started again. Of course it's not the characters' fault. The problem lies with the author. Take Stephen King, who admitted that writing working-class characters is more difficult nowadays because his own circumstances have changed. "It is definitely harder,"King said."When I wroteCarriemany years ago, I was one step away from physical labour." This is also true for characters' ages, added King."When you have small children, it is easy to write young characters because you observe them and you have them in your life all the time. But your kids grow up, it's been harder for me to write about this little 12-year-old girl in my new book because my models are gone." For other authors, such as Karen Fowler, there's one quality that can stop a character in its tracks: boredom."I had particular problems with the main character in my historical novelSister Noon,"she says."She had attitudes about race and religion that seemed appropriate to me for her time and class, but they were not attitudes I liked. Eventually I grew quite bored with her. You can write a book about a character you dislike or a character you disagree with, but I don't think you can write a book about a character who bores you." According to Neel Mukherjee, it was Adinath, a character inThe Lives of Others, who made him work the hardest."I think I struggled because it's difficult to write a character whose most prominent personal feature is weakness, as Adinath's is, without making that feature define him,"Mukherjee says. But a troublesome character is far from an unwelcome guest, he continues, arguing that "when characters work against the author they come alive and become unpredictable". "That is a fantastic thing to happen,"Mukherjee says."I celebrate it. It is one of the great, lucky gifts given to a writer."

[EX Q]: Article: Being considered a leader in our society is indeed of high praise.Leadership means power, commands respect and, most important, encourages achievement.Unlike vitamin C, leadership skills can't be easily swallowed down.They must be carefully cultivated. Different from popular belief, most good leaders are made, not born.They learn their skills in their everyday lives.But which do they develop? How do they (and how can you) get others to follow? Always give credit.Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes.Giving public credit to someone who has earned it is the best leadership technique in the world.It is also an act of generosity that's never forgotten. Giving credit is more effective than even the most constructive criticism , which often hurts rather than helps.Kenneth Blanchard, the author of The One-Minute Manager, agrees. "Catch people doing something right!" he says.Then tell everyone about it. Take informed risks." The best leaders know that taking a risk is not a thoughtless exercise," says management adviser Marilyn Machlowitz."Sky divers don't go up in an airplane without checking the parachutes beforehand." Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge.But if you want to be a leader, you must learn to fail - and not die a thousand deaths.Pick yourself up and start all over again. Encourage enthusiasm ."When people understand the importance of work, they lend their mental strengths," says Lee Ducat.But when they get excited about the work, all their energy gets poured into the job.That's a great force! Is this the best way to create excitement? Be enthusiastic your-self - You will be followed by everyone.
