| Several pieces of advice I've gotten in my life have really made a difference. "Be 1 to people." This sounds quite common, but I'll never 2 my father telling me that. I was ten, and I had been rude to someone. He said, "There is no 3 in being rude to anyone at any time. You never know who you're going to meet later in life. 4 , you don't change anything by being rude. 5 you don't get anywhere." " 6 that you can do anything you want to do. Don't let anyone say, 'You're not 7 enough…it's too hard…it's a bad 8 …no one has done that before…girls don't do that. My mom gave me that advice in 1973. And it 9 me to never worry about what others were saying about my 10 direction. "Always do the 11 job you can do at whatever you're assigned, even if you think it's 12 ." Jerry Parkinson, an assistant advertising manager and my boss at P&G, told me this in 1979. Here I had just 13 from Harvard Business School(HBS), and I was assigned to determine 14 the hole in the Ivory shampoo bottle should be: 3/8 of an inch or 1/8 of an inch．I did research, focus groups …and I would come home at night 15 how I had gone from HBS to this. But later I realized that any job you're given is a(n) 16 to prove yourself. "Don't be a credit hog(吝惜赞扬的人). If you're 17 in the neighborhood of good things, good things will 18 to you." Tom Tierney, who was my boss at Bain in 1981 and is now on the eBay board, told me this. It's 19 ? You get ahead by crediting other people. Finally, in 1998, I was in New York 20 the big celebration as eBay went public(上市). My husband is a doctor. I called into his operating room and told him the great news. And he said, "That's nice." | ||||
