????近日，謝麗爾?桑德伯格話題不斷。上周，我們在《財富》（Fortune）網站的“明信片”（Postcards）專欄回顧了《紐約時報》（the New York Times）關于桑德伯格的一篇人物特寫。文章指出，桑德伯格對于年輕商界女性的期待似乎絲毫不亞于她作為Facebook的首席運營官對這家公司所表現出來的雄心。簡而言之就是：放手去做，主宰世界。

????本周六，CNN.com網站發表了一篇文章，標題是《怎樣才能造就更多的桑德伯格？》（How to have more Sheryl Sandbergs.）。答案何在？作者寇妮?E.馬丁和凱蒂?奧倫斯坦認為，關鍵在于“同伴壓力”。

????兩位作者就職場女性不夠進取的原因給出了自己的看法：“我們很少想過要做出一些特立獨行的事情來，比如寫一篇意見書，要求老板給自己升職等等。就算想過，也不會付諸行動。畢竟，身邊的姐妹們和女同事都不這樣做，我們為什么要這樣做呢？”

????換句話說，只有社會上涌現更多的桑德伯格，才能造就更多的桑德伯格。

????如今，《財富》500強企業的“掌門”當中，只有18人是女性，我們顯然需要更多的女性榜樣。排名第34的大型石油企業——巴西石油公司（Petrobras）前不久剛任命格拉薩?福斯特為公司歷史上第一位女性CEO。這是個可喜的進步，不過企業高層的“男女平等運動”進展還不夠快。

????就在我們尋找女性典范之時，我恰巧碰到了一位女強人來訪。當年，正是她給了《財富》雜志靈感，創造性地推出了“最具影響力女性排行榜”（Fortune Most Powerful Women）。1996年，時任廣告巨頭奧美（Ogilvy & Mather，隸屬于WPP集團）CEO的夏洛特?比爾斯登上了《財富》封面，成了我筆下的封面故事《女性的性別與權力》（Women Sex & Power）的主人公。如今76歲的她依然寶刀不老，最近更是推出了一部新書，名為《我寧愿當頭兒》（I'd Rather Be in Charge）。她路過我家時，進來坐了一會。我們討論了一下女性與權力的問題。

????她認為，當今女性領導者太少的原因是：她們沒有什么模式可以遵循。

????“人們要求女性展示領導才能的時候，她們常常會不知所措，因為她們對領導別人沒什么概念，”比爾斯對我說。

????比爾斯說，雖然人們普遍認為女性比男性更加情緒化，但是喜歡在辦公場合公開宣泄情緒的恰恰是男性。這一點給男性帶來的好處是：“男性可以真實地表達自己的感受，不僅讓人難以忘懷，而且令人信服。”

????Sheryl Sandberg keeps on giving. Journalistically, that is. Last week, here on Postcards, we riffed on the New York Times profile of Sandberg, whose ambition for young women in business seems to match her ambition for Facebook, where she is COO. That is: Just do it...take over the world.

????On Saturday, CNN.com ran a story titled "How to have more Sheryl Sandbergs." The key? "Peer influence," posed the authors, Courtney E. Martin and Katie Orenstein.

????The authors explained what results when too few peers go for it, career-wise: "In many cases, the impulse to do something out of the norm of our peer group, like write an opinion piece or ask for a promotion, has simply never occurred to us. If it does, we don't act on it. Our girlfriends aren't doing it. Our female colleagues aren't doing it. Why should we?"

????In other words, we need more Sheryl Sandbergs to create more Sheryl Sandbergs.

????Today, when only 18 women lead Fortune 500 companies, we need more role models. Graca Foster was just designated the first female CEO of a major oil company: Brazil-based Petrobras, No. 34 on Fortune's Global 500. Great, but progress toward equality at the top remains slow.

????As we look for new models and peers, coincidentally, I had a recent visit from the woman who sparked the creation of Fortune Most Powerful Women. In 1996, Charlotte Beers, who was then CEO of ad giant Ogilvy & Mather (WPP), appeared on Fortune's cover for a story that I wrote called "Women Sex & Power." Now 76 and still irrepressible, Beers has a new book called "I'd Rather Be in Charge," and she stopped by to compare notes on women and power.

????Why too few women are taking charge today, as she sees the situation: There is no blueprint for women leaders to follow.

????"When asked to show their leadership capacity, women miss the cues because they don't know what leadership is supposed to look like," Beers told me.

????While women are generally viewed as more emotional than men, it is the men, Beers says, who tend to display emotion more openly in the office. And to their advantage: "Men can express exactly how they feel and make it memorable and persuasive," she says.

????As for getting promoted at work, men are much more adept: "Men know their bravery threshold, how resilient they are, and whether they can bluff their way through," Beers contends. Men's success largely relates to playing sports in their youth--which girls would be wise to do more of too.

????Women at work, bound to a narrower band of socially acceptable behavior, often question--or even worse, turn down--promotions. This is what Sandberg, 42, warns against in her classic Fortune essay, "Don't Leave Before You Leave." Instead of reacting to a promotion opportunity with a timid "Are you sure?," Beers favorite line: "What makes you think I can do this?"

????Good advice. The ad maven from the Mad Men era got me wondering: How many women will we see at the top decades from now, when Sandberg delivers her memoirs?
