"When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on earth and aren’t pessimistic, you don’t understand data. But if you meet the people who are working to restore this earth and the lives of the poor, and you aren’t optimistic, you haven’t got a pulse."

She suffers as a miser. She must be miserly with her pleasures, as well. I wonder if sometimes she doesn't wish she were free of this monotonous sorrow, of these mutterings which start as soon as she stops singing, if she doesn't wish to suffer once and for all, to drown herself in despair. In any case, it would be impossible for her: she is bound.
