A man who has taken your time recognises no debt; yet it is the one he can never repay.
Seneca the YoungerRefuse to let the thought of death bother you: nothing is grim when we have escaped that fear.
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.
