There is nothing that we can properly call our own but our time, and yet everybody fools us out of it who has a mind to do it.

Hold fast then to this sound and wholesome rule of life; indulge the body only as far as is needful for health.

As long as you live, learn how to live.

Poverty needs much, avarice everything.
