Here’s the important quote:
By the early 1990s, when the Nobel committee began investigating the possibility of awarding Dr. Nash its memorial prize in economics, his illness had quieted. He later said that he had simply decided that he was going to return to rationality.
“I emerged from irrational thinking, ultimately, without medicine other than the natural hormonal changes of aging,” he wrote in an email to Dr. Kuhn in 1996.

Photographer Tom Zimberoff on portraits:
I think a good photographer photographing people will do most of the work before they ever place a camera between themselves and their subject — spend as much time with that person as possible intimately watching them, seeing how they move and how they interact with their environment, and listening to what they have to say, and understanding what their interests are so you can juxtapose some of those ideas with your own.
