No one can confidently say that he will still be living tomorrow. - Euripides

Rhesus. Thy way is mine, friend. Straight I run my race
In word and deed, and bear no double tongue.

Silver and gold are not the only coin; virtue too passes current all over the world.

but soon you will be in a hurry to go to your chamber back again: for you are soon changed, and are pleased with nothing. Nor does what is present delight you, but what is not present you think more agreeable. It is a better thing to be sick, than to tend the sick: the one is a simple ill, but with the other is joined both pain of mind and toil of hands. But the whole life of men is full of grief, nor is there rest from toils. But whatever else there be more dear than life, darkness enveloping hides it in clouds. Hence we appear to dote on this present state, because it gleams on earth, through inexperience of another life, and the non-appearance of the things beneath the earth. But we are blindly carried away by fables.
