The Unquenchable Desire

In life, we want a lot.
We are here to ultimately fulfill our desires.
The luckiest ones of us all,
Are the ones who know what that will take.
The ones who are not as fortunate;
Spend a lot of time trying to figure out
What it will take...
...Until their time runs completely out.

But the worst of all,
Is still being alive
When you finally realize
That nothing will ever satisfy you.
