Laziness is a sin. Everyone knows that we have probably all had lectures pointing out that
Laziness can actually be helpful. Like procrastinators some people may look lazy when they are really thinking, planning, contemplating, researching. We should all remember that great scientific discoveries occurred by chance. Newton wasn't working in the orchard when the apple hit him and he devised the theory of gravity. All of us would like to have someone "lazy" build the car or stove we buy, particularly if that "laziness" were caused by the worker's taking time to check each step of his work and to do his job right. And some- times, being "lazy"--that is, taking time off for a rest--is good for the overworked students or executives. Taking a rest can be particularly helpful to the athlete who is trying too hard or the doctor who is simply working himself overtime too many evenings at the clinic. So be careful when you're tempted to call someone lazy. That person may be thinking, resting, or planning his or her next work.
