Footprints in the sands of time ...

Lives of great men all remind us
We can make our lives sublime,
And, departing, leave behind us
Footprints on the sands of time ;

Footprints, that perhaps another,
Sailing o'er life's solemn main,
A forlorn and shipwrecked brother,
Seeing, shall take heart again.

Let us, then, be up and doing,
With a heart for any fate ;
Still achieving, still pursuing,
Learn to labor and to wait.

~ H.W. Longfellow - A Psalm of Life
