Everything runs to excess; every good quality is noxious if unmixed.

I think there is only one quality worse than hardness of heart, and that is softness of head.

It costs a lot to build bad products.

It is the quality of our work which will please God and not the quantity.

Many individuals have, like uncut diamonds, shining qualities beneath a rough exterior.

Quality means doing it right when no one is looking.

Reprobate silver shall men call them, because the Lord hath rejected them.

The best is the cheapest.

The quality of the imagination is to flow and not to freeze.

There is hardly anything in the world that some man cannot make a little worse and sell a little cheaper.
