"For many doctors the achievement of a published article is a tedious duty to be surmounted as a necessary hurdle in a medical career."

Previous Quote

The successful producer of an article sells it for more than it cost him to make, and that's his profit. But the customer buys it only because it is worth more to him than he pays for it, and that's his profit. No one can long make a profit producing anything unless the customer makes a profit using it.
