I can look at a product and tell you exactly how it's doing. What wears me down is watching a good, careful decision get overruled because a number twitched the wrong way. I know what the data can't see, and I'm tired of it winning anyway.
More people experience this than they realize.
You can read a product clearly, but you're worn down when numbers override the craft.
If this sounds familiar, the Library can help you find the bigger picture.
