Seize the day [Carpe diem]: trust not to the morrow.
While we're talking, time will have meanly run on... pick today's fruits, not relying on the future in the slightest.
I have lived: tomorrow the Father may fill the sky with black clouds or with cloudless sunshine.
Frugality is one thing, avarice another.
Who knows whether the gods will add tomorrow to the present hour?
Fierce eagles breed not the tender dove.
