请翻译以下文字 The Power of Optimism Martin Seligman has been studying optimists and pessimists for 25 years. He is a psychologist and the author of bestselling books that help people to be more optimistic. In his studies of world-class athletes and top performers in the business world, Seligman found that optimists perform better when they encounter difficult situations than pessimists do. According to Seligman, “When pessimists come up against an obstacle, they often quit ; when optimists meet an obstacle, they try harder.” An optimist stays in the game and instead of seeing a problem, looks for a solution. One world-class athlete who stayed in the game and is a perfect example of the power of optimism is the cyclist Lance Armstrong. In 1996, Armstrong was diagnosed with advanced testicular cancer that had spread to his lungs and brain. His doctors were not optimistic, but he was. Instead of feeling down and defeated by his serious condition, Armstrong felt challenged and prepared for his future . He found chemotherapy treatments that would not damage his lungs permanently (because a world-class cyclist needs strong lungs). He rode his bicycle 80 to 100 kilometers a day, even though he was so sick that it was difficult for him to get out of bed. And, he had his sperm frozen so that he could have children someday, even though he was single at the time. Armstrong survived cancer and won the Tour de France seven times. He has three children, a boy and twin girls. Lance Armstrong has been called a “hope machine” and is an inspiration for those of us who need help being optimistic.
