20、失败是成功之母（名人演讲）
Being successful is hard. You won’t necessarily succeed at everything the
first time you try. That’s okay. Some of the most successful people in the
world are the ones who’ve had the mostfailures. J.K. Rowling’s -- who

team. He lost hundreds of games and missed thousands of shots during his
career. But he once said, “I have failed over andover and over again in my life.
And that’s why I succeed.”
