I'm excited about the opportunities with mobile phones and being able to receive information on the go and relevant to what I'm doing at that moment in time.

Work smart. Get things done. No nonsense. Move fast.

I have tried to be a leader. I have tried in my role of being one of the first women at Google, let alone the first woman to have a baby, to really try to set the tone that this is a great place to work for diversity reasons.

Rarely are opportunities presented to you in a perfect way. In a nice little box with a yellow bow on top. 'Here, open it, it's perfect. You'll love it.' Opportunities -- the good ones -- are messy, confusing and hard to recognize. They're risky. They challenge you.

It's important for me to show my children the richness of life and be a role model. I find that my organizational and management skills are tested more at home than at work!
