"He who cannot command himself should obey.

And many can command themselves, but much is still lacking before they can obey themselves."

~ Friedrich Nietzsche, 19th century German philosopher

from Thus Spoke Zarathustra: A Book for All and None

Self-mastery: to be able not only to "command" ourselves but also to "obey" those orders.

Few things are as powerful. As da Vinci (and sooo many others) teach us, "One can have no smaller or greater mastery than mastery of oneself."

Here's to our mastery.
