Decus et pretium recte petit experiens vir.
The man who makes the attempt justly aims at honour and reward.

Doctors coin money when they do procedures—family practice doesn't have any procedures. A urologist has cystoscopies, a gastroenterologist has gastroscopies, a dermatologist has biopsies. They can do three or four of those and make five or six hundred dollars in a single day. We get nothing for the use of our time to understand the lives of our patients. Technology is rewarded in medicine, it seems to me, and not thinking.

For science is ... like virtue, its own exceeding great reward.

The process of preparing programs for a digital computer is especially attractive, not only because it can economically and scientifically rewarding, but also because it can be an aesthetic experience much like composing poetry or music.

We find that one of the most rewarding features of being scientists these days ... is the common bond which the search for truth provides to scholars of many tongues and many heritages. In the long run, that spirit will inevitably have a constructive effect on the benefits which man can derive from knowledge of himself and his environment.

We must remember that in nature there are neither rewards nor punishments—there are consequences.

Working is beautiful and rewarding, but acquisition of wealth for its own sake is disgusting.
