We are all of a piece.

We cannot have an honest character, a complete, untarnished career, when we are constantly slipping rotten hours, defective material and slipshod service into our work.
The man who has dealt in shams and inferiority, who has botched his work all his life, must be conscious that he has not been a real man; he can not help feeling that his career has been a botched one.
To spend a life buying and selling lies, dealing in cheap, shoddy shams, or botching one's work, is demoralizing to every element of nobility.
Beecher said he was never again quite the same man after reading Ruskin.

You are never again quite the same man after doing a poor job, after botching your work.

You cannot be just to yourself and unjust to the man you are working for in the quality of your work, for, if you slight your work, you not only strike a fatal blow at your efficiency, but also smirch your character.

If you would be a full man, a complete man, a just man, you must be honest to the core in the quality of your work.
No one can be really happy who does not believe in his own honesty.
