Who drives fat oxen should himself be fat.

Every period of life is obliged to borrow its happiness from time to come.

Timidity is a disease of the mind, obstinate and fatal; for a man once persuaded that any impediment is insuperable has given it, with respect to himself, that strength and weight which it had not before.

Where no man thinks himself under any obligation to submit to another, and, instead of co-operating in one great scheme, every one hastens through by-paths to private profit, no great change can suddenly be made; nor is superior knowledge of much effect, where every man resolves to use his own eyes and his own judgment, and every one applauds his own dexterity and diligence, in proportion as he becomes rich sooner than his neighbour.

A vow is a snare for sin

Such is the state of life, that none are happy but by the anticipation of change: the change itself is nothing; when we have made it, the next wish is to change again.

So many objections may be made to everything, that nothing can overcome them but the necessity of doing something.
