Seize The Day

I didn't know the original quotation, so here it is:

Carpe Diem, Quam Minimum Credula Postero.

-- Quintus Horatius Flaccus

Or for those of us who don't spend a lot of time speaking Latin, a dead unspoken language, here's the English:

Seize the day, trust no tomorrows.

-- Quintus Horatius Flaccus
