At Newsweek Daily Beast’s fourth annual Women in the World Summit, Tina Brown said the glass ceiling is a “luxury” compared to the atrocities women in the rest of the world face, like the honor killings in Pakistan and the tens of thousands of rapes in Syria.

In her opening remarks Thursday at New York’s Lincoln Center, Brown gave credit to Facebook’s Sheryl Sandberg for “starting the conversation” about the lack of female leaders in business with her buzzed-about book Lean In. However, she stressed, there is still much work to be done.

“Leaning in can only be a part of the strategy. Leaning in works only in places where women are close enough to reach their rightful goals,” said Brown.

“Our mission at this summit isn’t just to lean in, but to lean ON — lean ON corporations to change the pitiful representation of women in board rooms, lean ON prosecutors to commit to end rampant sexual violence, lean ON the courts in Latin America to put an end to punitive violence against women, lean ON the pimps who sell girls for sex and the johns who buy them, lean ON the clerks of all religions who condone or turn a blind eye to the abuse of women and deny their fundamental rights, lean ON brothers who murder their sisters in so-called honor killings, lean ON entire governments to safeguard the rights and well-being and free up the economic potential of all their citizens. Lean ON.”
