…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 heart for any fate;
Still achieving, still pursuing
Learn to labor and to wait.

–Henry Wadsworth Longfellow
