It's hard to keep things moving. And that's always a big trick. I think for me, the key is setting really big goals. And, you know, with YouTube, I think we've had tremendous leadership, both with the founders and now with Salar, who's been running it.

I am involved in the land of a leonine and brave people, where every foot of the ground is like a well of steel, confronting my soldier. You have brought only one son into the world, but everyone in this land can be called an Alexander.

I have always loved and avidly read the novels of Jack London, Jules Verne and Ernest Hemingway. The characters depicted in their books, who are brave and resourceful people embarking on exciting adventures, definitely shaped my inner self and nourished my love for the outdoors.

I am utterly amazed, utterly enchanted! I have a precursor, and what a precursor! I hardly knew Spinoza: that I should have turned to him just now, was inspired by instinct.

Bill Gates has always been a mentor and inspiration for me even before I knew him. Just growing up, I admired how Microsoft was mission-focused.

It's hard to remember for you guys, but for me it's like yesterday I was driving the packages to the post office myself, and hoping one day we could afford a forklift.
