As it happens, some of us,
On our way through this life
Will work the great puzzles of this world,
And some will not.
And of those who work them,
Some work several,
While others, only one or two.
And some will be keen to realize
That merely venturing to work a puzzle
Brings no guarantee of solving it at all—
Nor that he would ever even realize if
If he thought he had it solved, but did not.
