To make an apple pie from scratch,
you must first invent the universe.

Carl Sagan

If a man does not keep pace with his companions,
perhaps it is because he hears a different drummer.
Let him step to the music which he hears,
however measured or far away.

Henry David Thoreau

"Twinkle, twinkle little star,
How I wonder what you are.
Up above the world so high,
Like a diamond in the sky,
Twinkle, twinkle little star,
How I wonder what you are."

Jane Taylor (1783-1824), Rhymes for the Nursery [1806], The Star

Some people see things as they are and ask 'Why?';
I dream things that never were and ask 'Why not?'

George Bernard Shaw (and RFK)
