Simple is clever. Complicated just means you haven’t been clever enough to reduce ‘it’ to its essence.

Simplicity does not precede complexity, but follows it.

UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.

I have learned that any fool can write a bad ad, but that it takes a real genius to keep his hands off a good one.
