Just a lovely quote from the late Merce Cunningham, that I randomly came across in Time last month.
It's more relevant to next week's discussion (Phelan and Reason). But there ya go.
"You have to love dancing to stick to it. It gives you nothing back, no manuscripts to store away, no paintings to show on walls and maybe hang in museums, no poems to be printed and sold, nothing but that single fleeting moment when you feel alive. It is not for unsteady souls."
