Henry Wadsworth Longfellow said this quote

Lives of great men all remind us We can make our lives sublime, And, departing, leave behind us Footprints on the sand of time; Footprints, that perhaps another, Sailing o'er life's solenm 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.
