In the book of life, the answers aren't in the back.

To Be Very fresh let me start with my title Psalm of Life..... Its that sacred song which life sings for us and sometime we sing for life.

TELL me not, in mournful numbers,

Life is but an empty dream ! —
For the soul is dead that slumbers,
And things are not what they seem.

Not enjoyment, and not sorrow,
Is our destined end or way ;
But to act, that each to-morrow
Find us farther than to-day.

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 !

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

Dont get confused , we don't sing this song but it is beautifully explained by Henry Wadsworth Longfellow in his poem.
