Sunday comes from Old English “Sunnandæg," which is derived from a Germanic interpretation of the Latin dies solis, "sun's day." Germanic and Norse mythology personify the sun as a goddess named Sunna or Sól.
“Don’t judge each day by the harvest you reap but by the seeds that you plant.”
Robert Louis Stevenson
"Don't waste a single Sunday. If you don't waste Sunday's, you will be less likely to waste Monday's, Tuesday's and Wednesday's."
-Matthew Kell, Resisting Happiness
