What Zen Scanner said

What
did Zen Scanner say?

Rapidly diminishing marginal utility associated with consumption of a fixed amount of a "career" causes the gifted to require a new life focus to derive the same utility they once did when the earlier pursuit was fresh.
The Pareto reference has me confused, as Pareto efficiency generally refers to trade-offs in utility from various changes in group consumption, not at the individual level. I suspect Zen is using Pareto here in the engineering--not economics--context as a representation of an efficient frontier for the individual in terms of career choices, etc, with multidimensional trade-offs. Zen, do I understand you correctly?
