Eternal vigilance is not only the price of liberty, but of every other good thing.

My unhappy vigilance is every moment discovering some petulance of accent, or arrogance of mien, some vehemence of interrogation, or quickness of reply, that recals my poverty to my mind, and which I feel more acutely, as I know not how to resent it.

He watched me; and his vigilance was a sickness to my heart.

Vigilance is a never-failing sign of value!"
