"The fundamental principles which govern the handling of postage stamps and of millions of dollars are exactly the same. They are the common law of business, and the whole practice of commerce is founded on them. They are so simple that a fool can't learn them; so hard that a lazy man won't."
- P. D. Armour
"Business is like oil. It won't mix with anything but business."
- J. Graham
"Anybody can cut prices, but it takes a brain to produce a better article."
- P. D. Armour
