Of life and fleeting visions

I have this vision,
A plan laid out before,
Of how my life should pan,
Ere I reach the other shore.

It is not detailed -
Only blurry does it appear,
Yet, just on this vision mere,
I move forth relentless,
Pursing something elusive -
Some lofty ambition, some zenith,
That I aspire to scale,
Yet what does doing so entail?
Of that, I know no jot.

Frustrating is this, I find,
The lack of clarity does play on my mind.
But then, perhaps, this is how it is meant to be,
Perhaps there is reason to why I can't, the future see,
Perhaps life would not such fun be,
Sans the exhilaration of discovery.
