根据材料回答题:AAfter working long hours On her feet everyday in the operating ,room, Taryn Rose' knew a lot about foot pain.But unlike most of her colleagues(同事),she turned her pain into money: Today she is the boss of Taryn Rose International, a $528 million company that makes nice and comfortable shoes.
At the beginning, Rose realized the only thing that could stop her was fear of ,failure."I couldhear my friends and family saying, 'Why did you leave a good job?' If I failed, would I be okay facing them? And: t thought, 'So what? I can go back for further study in medicine.' I started to accept that it would be okay to say, 'I failed, but I tried.' Once I was comfortable with that th6fight, the fear came to an end.I realized I feared regret more than failure.And after you turn to the path you choose, there is nothing acceptable but Success"
Now, Rose has no regrets about leaving medicine."What I'm doing is not all that different what I Was doing as a doctor.The goal is the same: to relieve (减轻) pain.A former professor told me: 'You're helping hundreds of thousands of women with your shoes.As a doctor, you would have helped only the few who went to your office.You're having a much greater effect.'
Looking back, Rose admits she caught a couple of lucky breaks."To me, luck is about being prepared for those opportunities (机会) that come knocking.You have to have an open mind, the right skilis and all your senses working 'to see what opportunities present themselves.Luck can open the door, but you still have to walk through it."Beforestarting:her shoe business, Taryn Rose was a A．nurse
