When will I know it all?

As a child, I was an inveterate question-asker.
Although, I've been told,
I would never stick around long enough for the answer
or answer the question myself, in the same breath.

One question I recall asking my father periodically was:
When will I know it all? when will I finish learning?

The looks of indulgence he shot me should have clued me in,
but little did I know.

I recall sometime in my 14th year
when revelation hit me, how disappointed I felt.
I will never learn it all, know it all.
Because the more I learn, the more I realize how much there is out there!

And if I knew then, what I know now...
Life will unfold as it may.
Just as one thinks we've got the the knack of it,
it slides away from under one's feet,
leaving one staring at the sky.

Which is not always a bad place to be.
Cloud-gazing is good for the soul.
Looking up allows us to rise above our circumstances
to dream and think happier thoughts.
The sky is only the limit
if the imagination acquiesces.     

What do you see up there?
