And if you're going to criticize me for not finishing the whole thing and tying it up in a bow for you, why, do us both a favor and write your own damn book, only have the decency to call it a romance instead of a history, because history's got no bows on it, only frayed ends of ribbons and knots that can't be untied. It ain't a pretty package, but then it's not your birthday that I know of so I'm under no obligation to give you a gift.

Welcome to the human race. Nobody controls his own life, Ender. The best you can do is choose to fill the roles given you by good people, by people who love you.

If you give orders and explain nothing, you might get obedience, but you'll get no creativity.

Explaining to your men doesn't weaken their respect for you, it proves your respect for them.

Two sides of the same coin, but which side is which?
