Why do I strive, for that which I can not possess?

Why do I strive, for that which I can not possess?
Is the sun’s caress
Not enough
That I must grasp at other stuff?
Caught
On the wheel
Of thought
I feel
That I aught …

Be done
With useless thinking.
I shall at life’s fountain be drinking,
For existence doth run
Away,
And I can not reclaim a single day
Spent,
In thinking on a nymph’s unknowable scent.
