I’m presently reading Mary Doria Russell’s The Sparrow, and came across this passage that I really liked:
He was always working or laughing or studying, and his intensity and humor made him seem ageless. She knew something of his life, having worked with him, and recognized him as one of her own kind: an eternal beginner, starting over and over in a new place in new circumstances, with new languages, new people, a new commission. They had this in common: the continual rushed confrontation with change, the feeling of being hothoused, forced to bloom early, the exhausting exhilaration of doing the unreasonable not just adequately but well and with grace.
It felt apropos.
