- William Strunk, Jr. and E B. White (The Elements of Style)

“Get rid of half the words on each page, then get rid of half of what’s

left.”

- Steve Krug (2006)

“Simplicity is the ultimate sophistication.” - Leonardo da Vinci

“Everything should be made as simple as possible, but not simpler.” - Albert Einstein

“Nothing is more simple than greatness; indeed, to be simple is to be great.” - Ralph Waldo

Emerson

“..in anything at all, perfection is finally attained not when there is no loner anything to add,

but to when there is no longer anything to take away..” - Antoine de St. Exupery
