There's no committee that says, 'This is the type of person who can change the world - and you can't.' Realizing that anyone can do it is the first step. The next step is figuring out how you're going to do it.

Let's abolish the term 'childish' because adults normally cause the largest problems.

Success on the front of women's rights will look like a world not only with obvious advances - where no girl is denied access to education, for instance - but also one with more subtle changes in how we regard gender and gender stereotypes.

The goal is not to turn kids into your kind of adult, but rather better adults than you have been.

Students read for tests and because their parents ask them to, but I think it's very important to tell children that you can read for fun, too, and to understand human spirit. It builds empathy.

We always reference kids but very rarely ask their opinion. Our inexperience might be what gives us the ability to teach our elders something, due to the fact that we are not jaded or cynical.

I realise I'm still a child, though I do feel older. I recently did an on-line test called 'What's Your True Age?' My result was 50-60 years old.
