The Imperial Service could win a war without coffee, but would prefer not to have to.

This is the most important thing I will ever say to you. The human mind is the ultimate testing device. You can take all the notes you want on the technical data, anything you forget you can look up again, but this must be engraved on your hearts in letters of fire. There is nothing, nothing, nothing, more important to me in the men and women I train than their absolute personal integrity. Whether you function as welders or inspectors, the laws of physics are implacable lie detectors. You may fool men. You will never fool metal. That’s all.

You have to be careful who you let define your good.

The dead cannot cry out for justice. It is a duty of the living to do so for them.

All great human deeds both consume and transform their doers. Consider an athlete, a scientist, an artist, or an entrepreneur. In service of their goals, they lay down time, energy and many other choices and pleasures; in return, they become most truly themselves. A false destiny may be spotted by the fact that it consumes without transforming, without giving back the enlarged self.
