My goal is very clear, and I wrote about it in Lean In, which is that women run half our companies and countries and men run half our homes. As much as I wish that could happen in four years, I don't think that's a likely time period. But I think it can happen sooner than we think. Part of it is having that aspiration and that goal.

I would love to meet J.K. Rowling and tell her how much I admire her writing and am amazed by her imagination. I read every 'Harry Potter' book as it came out and looked forward to each new one.

Done is better than perfect.
