Documentaries shouldn't just reflect the world: they should try and explain why reality is like it is.

I always have a reason for why I do something.

I think, a lot of times in Hollywood, the right idea comes along at the right time, and it becomes in retrospect, 'Wow, why didn't I think of that?'

Why can't you be both? Why can't I be on the basketball team but also be the student president?

I want to constantly get better. Why not just keep fighting? Until I get told that I can't anymore, then I'll move on.

Most of us tend to be swayed by what we read. Judges are not superhuman. They, too, are mortals. This is why they have to be exceptionally careful in rendering decisions, which cause unintended consequences.

Our failed population-centric approach to Afghanistan has only led to missed opportunities, which is why Afghanistan depends on donors for 90% of government revenues. A smarter, trade-centric approach will boost Afghanistan's long-run viability by weaning it off donor welfare dependency.

Of course I don't have a big serve. I have other weapons. That's why tennis is a nice sport.

Kids come out of the chute liking science. They ask, 'How come? Why? What's this?' They pick up stuff to examine it. We might not call that science, but it's discovering the world around us.

I'm in a Catch-22. If I don't go after a ball, I'm lazy, I'm not giving it 100 percent. If I do dive for the ball - which I did, and blew out my shoulder - it's, Why did I play it so hard?

I have seen entrepreneurs ask for hundreds of millions of dollars on a concept and try to sell because of 'their passion' for an idea. If the idea is that good, why wouldn't I cut you out and hire someone who is just as passionate for much, much less?

It's understandable why someone might not want to take on a book they think is emotionally hard.

There are many things to improve. I'm not nearly a perfect player, that's why I need to keep going.

At some point, someone will come up with an airtight argument as to why they should have a cloned child. At that point, cloning will be acceptable.
