Can't work / won't work

Here you see, are two kinds of work - one good, the other bad; one not far removed from a blessing, a lightening of life; the other a mere curse, a burden of life.

What is the difference between them, then? This one has hope in it, the other has not. It is manly to do the one kind of work, and manly also to refuse to do the other.

- William Morris, Useful Work Versus Useless Toil

The gaggery and gilt of a million years will not prevail... The poet shall not spend his time in unneeded work.

- Walt Whitman, Leaves of Grass
