We have many routes to success in agricultural economics: extension education, resident teaching, advising, research, and public service. In selecting problems to study we must be sensitive to needs of all our clientele. Several production economics concepts are relevant to allocating our own efforts.

We need to use heuristics, intuition, deduction, and induction, though consideration of science's ideal and real types shows that all these mental processes are fallible. We need special theories that have broad application. Replication deserves high priority. A few thoughts on the manuscript review process are presented.
