Why save time? (Ghandi + Gilbreth quotes)

Had this interaction with Hunter Walk on Twitter:

Cheaper by the Dozen Book Cover

The full quote, from Cheaper by the Dozen (Amazon):

Someone once asked Dad: “But what do you want to save time for? What are you going to do with it?” “For work, if you love that best,” said Dad. “For education, for beauty, for art, for pleasure.” He looked over the top of his pince-nez. “For mumblety-peg, if that’s where your heart lies.”
