Happy Or Not, Here It Comes

If you have best health and fitness
No illness to disrupt your feat
But you still make dark gloom your forecast
Your accomplishments will then delete
If you have the greatest wealth and gain
Which affords material things
But still have overriding drabness
It is just like what poverty brings
If you have true love and friendship
With affection held in most hearts
But still have black misery brooding
You'll experience how loneliness smarts
If you have highest rank and fame
With respect and honor from all
But still have an anguishing sadness
You'll know the "humpty-dumpty" great fall
If you have good luck and fortune
If you're favored in all you do
But still have a frown on your forehead
The advantage is erased from you
