Social media has created a historical shift from the historically powerful to the historically powerless. Now everyone has a voice.

Women don't take enough risks. Men are just 'foot on the gas pedal.' We're not going to close the achievement gap until we close the ambition gap.

Men can comfortably claim credit for what they do as long as they don't veer into arrogance. For women, taking credit comes at a real social and professional cost.

We have a problem with women in leadership across the board. This leadership gap - this problem of not enough women in leadership - is running really deep and it's in every industry. My answer is we have to understand the stereotype assumptions that hold women back.

The cost of stability is often diminished opportunities for growth.

Don't let your fears overwhelm your desire. Let the barriers you face-and there will be barriers-be external, not internal. Fortune does favor the bold, and I promise that you will never know what you're capable of unless you try.

No industry or country can reach its full potential until women reach their full potential. This is especially true of science and technology, where women with a surplus of talent still face a deficit of opportunity.
