I forget when I saw this poem, but it is so spot on.  I hope you have a great day today!

Look to this day,
for it is life, the very breath of life.
In its brief course
Lie all the realities of your existence;
the bliss of growth,
the glory of action,
the splendor of beauty.
For yesterday is only a dream,
and tomorrow is but a vision.
But today, well lived,
makes every yesterday a dream of happiness,
and every tomorrow
a vision of hope.
Look well, therefore, to this day.
