As women slowly gain power, their values and priorities are reshaping the agenda. A multitude of studies show that when women control the family funds, they generally spend more on health, nutrition, and education - and less on alcohol and cigarettes.

Many differences are rooted in biology and reinforced through culture, so it's important to acknowledge that. Because if you say men and women are the same and if male behaviour is the norm, and women are always expected to act like men, we will never be as good at being men as men are.

The exposed nature of life in the public square affects leaders' attitudes toward risk - and failure.

Obama seemed poised to realign American politics after his stunning 2008 victory. But the economy remains worse than even the administration's worst-case scenarios, and the long legislative battles over health care reform, financial services reform and the national debt and deficit have taken their toll. Obama no longer looks invincible.

No doubt, the White House thinks the American people know Obama's story. But since the Inauguration, we've seen only the president's present: his perfect family, his Ivy League elegance, his effortless mastery of complex issues. We never see him sweat. And we forget that he ever had to struggle.

1992 became known as the 'Year of the Woman' because so many of us were elected to public office that November, including a record six to the United States Senate.

That's not to say that women's priorities are better than men's. Rather, when women are empowered, when they can speak from the experience of their own lives, they often address different, previously neglected issues. And families and whole communities benefit.
