I'm very glad my mother didn't let me quit piano lessons at age 10. She said I wasn't old enough or good enough to make that decision, and she was right. I remember at the time I was shocked. I did not like that my mother said those things to me. But when I got a chance to play with Yo-Yo Ma or more recently with Aretha Franklin, I thought, I'm really glad she said what she did.

I think there are plenty of men out there who are capable and accomplished in their own realm. You don't have to be in the same field. I've often been asked, "Didn't you want to get married?" And of course I wanted to get married, but you have to fall in love and want to marry a particular person. You don't get married in the abstract. So, although there were people I felt I might have married, it just never happened.

Democracy is the most realistic way for diverse peoples to resolve their differences, and share power, and heal social divisions without violence or repression.

Our work has only begun. In our time we have an historic opportunity to shape a global balance of power that favors freedom and that will therefore deepen and extend the peace.

Great leaders never accept the world as it was and always work for the world as it should be

I think there's sometimes too much attention to a few people who do hold extreme views. Most Americans go about their lives living in communities that are increasingly multiethnic, increasingly multi-religious. And they are welcoming of people who are not like themselves. Now, I don't have rose-colored glasses about America, because I grew up in the segregated South. But I watch it every day. I think that Americans are very tolerant people.
