Norton Juster is the author of The Phantom Tollbooth.
"There was once a boy named Milo who didn't know what to do with himself — not just sometimes but always. When he was in school he longed to be out, and when he was out he longed to be in ... Nothing really interested him — least of all the things that should have."
It was, of course, the doldrums — his own special version of them.
