Then out spake brave Horatius,

And how can man die better

For the ashes of his fathers,
And the temples of his gods,
Churchill had a terrible lisp as a child. To combat it he memorized poems, plays and passages from books.
With Demosthenes as his inspiration he then spent hours each day standing in front of a mirror watching his mouth as he recited the passage. Not content until he could speak with confidence his lisp wouldn’t embarrass him.
