| Mark Gibson is a former gymnastics coach who once worked with many excellent athletes. He often tells a wonderful story about a 15-year-old 1 girl, Cindy, whose attitude brought out the best in everyone. Cindy wasn't a great 2 , but when she was in the gym, everyone complained less, worked harder, and, not 3 , achieved more. Cindy was such a powerful motivator 4 she could see nothing. When it was her turn to do the vault (跳马), mother would also 5 alongside her, and tell her how close she was to the vault. When her mom said, "Vault!", Cindy would reach out and jump, 6 her mother and herself. Cindy loved the sport and kept 7 because she and her mom refused to be defeated by her 8 . Mark called her the most 9 member of the team, not because of her 10 ability, but because of her heart and because she 11 a standard of perseverance (坚持) and courage that inspired others to get more out of themselves. Everyone who 12 her work hard to be the best 13 how much more they could get out of themselves. This is leadership---leadership by 14 . And we see this sort of leadership not only in 15 but also in families and in the workplace. Often the most important members of the team are not the 16 , most skilled, or most powerful. Instead, their 17 is in their attitude and their ability to inspire and 18 others with their optimism, enthusiasm, and determination. People who know how to get the best out of themselves get the best of others. There's no doubt that Cindy's 19 has a great effect on her teammates. A person's personality matters most because it comes from within and does not depend on 20 alone. | ||||
