I’ve often thought that the single most devastating cyberattack a diabolical and anarchic mind could design would not be on the military or financial sector but simply to simultaneously make every e-mail and text ever sent universally public. It would be like suddenly subtracting the strong nuclear force from the universe; the fabric of society would instantly evaporate, every marriage, friendship and business partnership dissolved. Civilization, which is held together by a fragile web of tactful phrasing, polite omissions and white lies, would collapse in an apocalypse of bitter recriminations and weeping, breakups and fistfights, divorces and bankruptcies, scandals and resignations, blood feuds, litigation, wholesale slaughter in the streets and lingering ill will.

Sayeth Master Yoda

This one's actually relevant for many of us. a reminder to stop obsessing about the future and worrying about tomorrow. Just focus on what you are doing now.

A Jedi must have the deepest commitment, the most serious mind. This one a long time have I watched. All his life has he looked away... to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing. Hmph. Adventure. Heh. Excitement. Heh. A Jedi craves not these things.
