Marissa Mayer: Supermarket check-out
玛丽莎•梅耶尔：超市收银员

Yahoo! chief executive Marissa Mayer was one of Google's earliest employees and has amassed an estimated fortune of $380m (£262m), according to Forbes.
据《福布斯》杂志，雅虎首席执行官玛丽莎•梅耶尔曾是谷歌公司最早雇员之一，其资产累计约有3.8亿美元（2.62亿英镑）。

But that wealth must have felt a long way away when she was working behind a till at a supermarket during high school.
这样一笔财富，对于当时埋头于超市收银台工作的高中生而言，真是任重道远。

"I learned a lot about work ethic from people who had been there for 20 years," she told the LA Times.
她对《洛杉矶时报》记者说：“在那里，我从那些工作长达20年的前辈身上学到了关于职业道德的诸多经验。

"They could do 40 items a minute over an eight-hour shift. I was pretty routinely in the 38-to-41 range. I was pretty happy about that. I have a good memory for numbers."
“在当班的八小时中，他们可一分钟刷完40项商品，我通常处在38至41项之间，对此我相当开心，我对数字记忆很敏感。”
