"It is difficult for men in high office to avoid the malady of self-delusion. They are always surrounded by worshippers. They are constantly, and for the most part sincerely, assured of their greatness. They live in an artificial atmosphere of adulation and exaltation which sooner or later impairs their judgment. They are in grave danger of becoming careless and arrogant. The chances of having wise and faithful public service are increased by a change in the Presidential office after a moderate length of time."
- Calvin Coolidge
