John Boyle O'Reilly Quote

How shall I a habit break?
As you did that habit make.
As you gathered, you must lose;
As you yielded, now refuse.
Thread by thread the strands we twist
Till they bind us, neck and wrist.
Thread by thread the patient hand
Must untwine, ere free we stand.
As we builded, stone by stoene,
We must toil, unhelped, alone,
Till the wall is overthrown.

A Builder's Lesson.
