Without certainty you cannot begin
Foundations always moving are not
For on such you can never build
But only to be moved and carried
Endlessly without rest always changed
Discarding the old attempting the new
But waste and futility, no mastery nor success
What knowledge gleaned very soon irrelevant
Here today, everything's changed tomorrow
Always a toddler, crippled for life
To stand for a while the pinnacle
To walk or run, foolishness, for falls
And you break, never crawling again
But for grace the sand steady as a rock
That you may know sand shift in winds
And to search for rock before you build
But not boast the death of certainty
