Where a tiny flaw or the slightest defect may cost a precious life, carelessness is as much a crime as deliberate criminality.
If everybody put his conscience into his work, did it to a complete finish, it would not only reduce the loss of human life, the mangling and maiming of men and women, to a fraction of what it is at present, but it would also give us a higher quality of manhood and womanhood.
Most young people think too much of quantity, and too little of quality in their work.

They try to do too much, and do not do it well.

They do not realize that the education, the comfort, the satisfaction, the general improvement, and bracing up of the whole man that comes from doing one thing absolutely right, from putting the trade-mark of one's character on it, far outweighs the value that attaches to the doing of a thousand botched or slipshod jobs.
We are so constituted that the quality which we put into our life-work affects everything else in our lives, and tends to bring our whole conduct to the same level.

The entire person takes on the characteristics of one's usual way of doing things.

The habit of precision and accuracy strengthens the mentality, improves the whole character.
On the contrary, doing things in a loose-jointed, slipshod, careless manner deteriorates the whole mentality, demoralizes the mental processes, and pulls down the whole life.
Every half-done or slovenly job that goes out of your hands leaves its trace of demoralization behind.
