Let's face it: Engineering companies in general have more men than women. Google has tried really hard to recruit women. On the other hand, we have a standard. Google tries to recruit the best engineers.

Learning to code makes kids feel empowered, creative, and confident. If we want our young women to retain these traits into adulthood, a great option is to expose them to computer programming in their youth.

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.

We are a consumer company and our success is directly linked to our users trusting us. Therefore we have the same incentive as the user: they want to see relevant advertising so their experience of Google is positive and we want to deliver it.

Things are always changing. Part of being successful here is being comfortable with not knowing what's going to happen.

Right now, offline and online are coming together because of smartphones.

I love taking an idea... to a prototype and then to a product that millions of people use.
