Some men storm imaginary Alps all their lives, and die in the foothills cursing difficulties which do not exist.
E. W. Howe

This is a work of fiction. All the characters in it, human and otherwise, are imaginary, excepting only certain of the fairy folk, whom it might be unwise to offend by casting doubts on their existence. Or lack thereof.
Neil Gaiman

I sometimes suspect that half our difficulties are imaginary and that if we kept quiet about them they would disappear.
Robert Staughton Lynd
