Nos vertus ne sont, le plus souvent, que de vices déguisés. - François de La Rochefoucauld

Ce qui nous rend la vanité des autres insupportable, c'est qu'elle blesse la nôtre.

We are sure to displease when we speak too long and too often of one subject, and when we try to turn the conversation upon subjects that we think more instructive than others, we should enter indifferently upon every subject that is agreeable to others, stopping where they wish, and avoiding all they do not agree with.

Indolence, thoroughly languid though it be, very seldom fails to be master; it interferes with all our plans and actions, and gradually wears down and destroys our passions and our virtues.
