It is not a difference between a stornger or weaker ditch digger, but a difference between a worker who is willing to work harder than another worker. If you take pride in your work, you should be completing it correctly,competently, and completely. BTW, this is unlike most students today. They turn in work-if it comes in at all-slipshod, unfinished, and usually late. They need to have some time spent on ditch digging to learn how hard work is and how they won't be paid until the job is completed correctly. If they take extra time, they will only be paid the amount of money that it would take a reasonable worker to complete the job.
