Can't by Edgar A. Guest

Can't is the worst word that's written or spoken;
Doing more harm here than slander and lies;
On it is many a strong spirit broken,
And with it many a good purpose dies.
It springs from the lips of the thoughtless each morning
And robs us of courage we need through the day:
It rings in our ears like a timely-sent warning
And laughs when we falter and fall by the way.

Can't is the father of feeble endeavor,
The parent of terror and half-hearted work;
It weakens the efforts of artisans clever,
And makes of the toiler an indolent shirk.
It poisons the soul of the man with a vision,
It stifles in infancy many a plan;
It greets honest toiling with open derision
And mocks at the hopes and the dreams of a man
