Leadership is about making others better as a result of your presence and making sure that impact lasts in your absence." (Harvard Business School definition of leadership)
I want to tell any young girl out there who's a geek, I was a really serious geek in high school. It works out. Study harder.
When I was in high school, I was voted most likely to succeed.
I gave a talk on gender stuff at Facebook one morning and a man didn't come. It was optional; he didn't have to come. But he sent a note saying, "I missed your meeting because I drove my kids to school so my wife could do something else. Thank you for making that possible." I think that employee is a loyal employee for Facebook and I think more companies should want that kind of loyalty.
