I love the challenge of starting at zero every day and seeing how much I can accomplish.

I try to seek out and surround myself with people who just percolate fresh, original, and creative ideas.

I had no idea when I went to college what I'd be doing. I took organic chemistry and did terribly, but I was good in English and art. I took many courses and participated in as many activities as I could. I learned a lot about every single thing.

Life is too complicated not to be orderly.

I admire the courage and self-reliance it takes to start your own business and make it succeed.

Don't be embarrassed by your achievements. Being an overarchiever is nothing despicable. It is only admirable. Never lower your standards.

I always thought I would be a teacher. And I think I actually lived up to my initial dreams, because what I do now is teach millions and millions of people many different kinds of things.
