Measuring nothing (with great accuracy)

Seth Godin (in 2014):

We keep coming up with new things to measure (like processor speed, heat output, column inches) but it's pretty rare that those measurements are actually a proxy for the impact or quality we care about. It takes a lot of guts to stop measuring things that are measurable, and even more guts to create things that don't measure well by conventional means.

One thousand percent.
