“I have a lot to weigh: the basis of public service, which I've given my life to, a career choice. And most importantly, what I want to do as a parent. I know something about the White House. That, I assume, is one of the reasons that President-elect Obama would like me to serve. But I also know something about what it means to a family.”

both quotes in a letter to William M. Milliken, New York November 1, 1930; as quoted in Voicing our visions, – Writings by women artists; ed. Mara R. Witzling, Universe New York, 1991, p. 227
1930s

The "Burke quote" she uses here is a common but disputed attribution.
UN Speech on the HeForShe campaign (2014)
Context: You might be thinking who is this Harry Potter girl? And what is she doing speaking at the UN. And it’s a really good question. I've been asking myself the same thing. All I know is that I care about this problem. And I want to make it better.
And having seen what I’ve seen — and given the chance — I feel it is my responsibility to say something. Statesman Edmund Burke said: “All that is needed for the forces of evil to triumph is for good men and women to do nothing.”
In my nervousness for this speech and in my moments of doubt I’ve told myself firmly — if not me, who, if not now, when. If you have similar doubts when opportunities are presented to you I hope that those words might be helpful.

Nina Paley on: Sita Sings the Blues: The Ramayana and 'Free Culture' (2009)
Context: Everyone wants me to make another movie and I'm like "Yeah, I'm doing quilts." Yeah, I have ideas. I have to be really, really obsessively moved. Like I have to have no other choice to do a project that takes that much time and it has to be a motivation other than just that I know that I will get approval for it. Much as I love approval, I mean it's extremely tempting. I want it. And I have a lot of doubts about following my muse when my muse leads me down some weird path. Again, like quilts. But I also know that if I do something just because I know people will approve of that, that's not really going to help me as an artist. So I'm not ruling out doing another film, but I'm only going to do it if I have no other choice, which was the case with Sita Sings the Blues.
