Now, what is "reasonable" field circus hours? What is "reasonable" activity? Anyone that has had a basic knowledge of economics should know about opportunity costs, marginal costs, and marginal benefits. Marginal cost is the cost of the next unit of activity, while the marginal benefit is the amount you reasonably expect to gain from that next unit. There is such a thing as diminishing returns--the more you do something, the lower the marginal benefit is. And the marginal cost usually goes up with each unit. Once the marginal cost equals the marginal benefit, that is the optimal amount. Anything more is beyond reasonable and always results in net loss. This goes as much for attendance at boasting sessions and volunteeering at a$$emblies as for field circus
right on the mark
The economic theory of diminishing returns: the point when a business venture gets so large it becomes unprofitable(General Motors was a prime example)
I think your correct in applying it to the preaching work as well. Many publishers putting 10 hrs have as much success as a pioneer putting 70 hs
