Philosophy's Time Poem by Shirley Harrison

Today is the day
today is the day, that we get to live our best day
let's not think about yesterday because the moment has past
nothing we can do to change the way in which we saw it
and tomorrow?
well it hasn't arrived and for some it won't
let's stay in today
making the best of what we have
forwarding into the then yesterday
ever knowing that we didn't waste a single moment dwelling on what was and what could be, because we actually know what is.
