How Much is Enough?

AT A PARTY GIVEN BY a billionaire on affluent Shelter Island, New York, author Kurt Vonnegut informs his friend, Joseph Heller, that their host had recently made more money in a single day than Heller had earned in total from his hugely popular novel, Catch-22.

“And what is that?” asks Vonnegut.
“Enough,” says Heller. “Enough.”
The story may be apocryphal—I’ve read a similar version featuring J.D.
