“I am sufficiently proud of my knowing something to be modest about my not knowing all.”

Something He Can Feel.
Song lyrics

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.

O interview (2003)
Context: I had been already trying to do Frida, but I would sit on my sorrows because it was so difficult. But now I was learning new things. And so I thought, this is what I want to do. I want to do one movie that if I die the next day, I know I left one thing in this world that I was very proud of, that other people can see, that meant something to me, that had my voice. Because God forbid I die tomorrow, I'm the bombshell for the rest of my existence. … Then I became very angry I said, I have become what they decided I am. When did I fall in this trap? Somebody decided I was this, and I became that. And I said, "I'm going to change it now. I'm going to define myself."

Black Boy (1945)

1880s, 1880, Letter to Theo (Cuesmes, July 1880)
Context: There is a great difference between one idler and another idler. There is someone who is an idler out of laziness and lack of character, owing to the baseness of his nature. If you like, you may take me for one of those. Then there is the other kind of idler, the idler despite himself, who is inwardly consumed by a great longing for action who does nothing because his hands are tied, because he is, so to speak, imprisoned somewhere, because he lacks what he needs to be productive, because disastrous circumstances have brought him forcibly to this end. Such a one does not always know what he can do, but he nevertheless instinctively feels, I am good for something! My existence is not without reason! I know that I could be a quite a different person! How can I be of use, how can I be of service? There is something inside me, but what can it be? He is quite another idler. If you like you may take me for one of those.
