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!

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.

There are unlimited opportunities for display advertising. In fact, we're in the process of massive change in the display industry - how it's bought, how it's sold, and how it's targeted.

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

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.

The reason I like my job is that I have this desire to create. I have this desire to create things and build things, and Google has enabled me to build and create things and to build products that are used by people all over the globe.
