To be thrown upon one's own resources is to be cast into the very lap of fortune; for our faculties then undergo a development and display an energy of which they were previosly unsusceptible.
Wise men learn by others' harms, fools scarcely by their own.
If you wouldn't live long, live well; for folly and wickedness shorten life.
Pain wastes the Body, Pleasures the Understanding.
A quarrelsome man has no good neighbours.
Never leave that till tomorrow which you can do today.
