At any rate, Henry Wadsworth Longfellow agrees (and he says it so much better than I). So instead of my ramblings, here is his poem:
A Psalm of Life
Tell me not, in mournful
number,
Life is but an empty
dream!
For the soul is dead that
slumbers,
And things are not what
they seem.
Life is real! Life is
earnest!
And the grave is not its
goal;
Dust thou art, to dust
returnest,
Was not spoken of the
soul.
Not enjoyment, and not
sorrow,
Is our destined end or
way;
But to act, that each
to-morrow
Find us farther than
to-day.
Art is long, and Time is
fleeting,
And our hearts, though
stout and brave,
Still, like muffled drums,
are beating
Funeral marches to the
grave.
In the world’s broad field
of battle,
In the bivouac of Life,
Be not like dumb, driven
cattle!
Be a hero in the
strife!
Trust no Future, howe’er
pleasant!
Let the dead Past bury its
dead!
Act,— act in the living
Present!
Heart within, and God
o’erhead!
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.
If poetry is not your thing, here's a clip from Sword in the Stone with some excellent lyrics towards the end of the song... but watch the entire thing because the whole song is pure genius.
