Unnatural, frantic, anxious work, work done under pressure of greed or fear or any other inordinate passion, cannot properly speaking be dedicated to God, because God never wills such work directly.  He may permit that, through no fault of our own, we may have to work madly and distractedly, due to our sins, and to the sins of the society in which we live.  In that case we must tolerate it and make the best of what we cannot avoid.  But let us not be blind to the distinction between sound, healthy work and unnatural toil.

-Thomas Merton
