People ought to think about measuring those things that make a difference to the person or people they serve.
Measure what you do and keep score of how much you are doing of what matters. If you are developer at a software company, perhaps your measure is Story Points per Sprint, number of Customer Reported Bugs fixed within SLA, and number of improvements/refactorings done on the existing codebase per Sprint, number of Unit Tests added, Code Coverage Improvements etc.
