As the soil, however rich it may be, cannot be productive without cultivation, so the mind without culture can never produce good fruit
Seneca the YoungerAs gratitude is a necessary, and a glorious virtue, so also it is an obvious, a cheap, and an easy one; so obvious that wherever there is life there is a place for it; so cheap, that the covetous man may be gratified without expense, and so easy that the sluggard may be so likewise without labor.
Seneca the Younger
