“There is a real joy in doing mathematics, in learning ways of thinking that explain and organize and simplify. […]. This inner motivation might lead us to think that we do mathematics solely for its own sake. That’s not true: the social setting is extremely important. We are inspired by other people, we seek appreciation by other people, and we like to help other people solve their mathematical problems. […] ⟨M⟩ost mathematicians don’t like to be lonely, and they have trouble staying excited about a subject, even if they are personally making progress, unless they have colleagues who share their excitement.”
—William P. Thurston, On proof and progress in mathematics, Bull. Amer. Math. Soc. (N.S.), 30(2): 161–177, 1994, p. 171.
