Ecclesiastes 1:2

“Futile! Futile!” laments the Teacher.
“Absolutely futile! Everything is futile!”
Ecclesiastes 1:2 New English Translation (NET)
 
“Vanity of vanities,”
    says the Preacher;
“vanity of vanities,
    all is vanity.”
Ecclesiastes 1:2 Modern English Version (MEV)
 
I think the following embodies quite nicely the sentiments expressed in this verse:
 
Dust In the Wind
Song by
Kansas
 
I close my eyes
Only for a moment, and the moment's gone
All my dreams
Pass before my eyes, a curiosity
 
Dust in the wind
All they are is dust in the wind
 
Same old song
Just a drop of water in an endless sea
All we do
Crumbles to the ground, though we refuse to see (ah, ah, ah)
 
Dust in the wind
All we are is dust in the wind
 
Oh, oh, oh
Now, don't hang on
Nothin' last forever, but the earth and sky
It slips away
And all your money won't another minute buy
 
Dust in the wind
All we are is dust in the wind (all we are is dust in the wind)
Dust in the wind (everything is dust in the wind)
Everything is dust in the wind
In the wind
